  • Dude....you learn this stuff when you are 17 years old or in first year off college. GO EDUCATE YOURSELF!!!!

  • Hi. Please take a fluid dynamics class. Good bye.

  • if i recall correctly this is stuff you learn at school more or less when you are 16-17 years old.... the person who made this video have some really big problem understanding trivial physics .....

  • Damn you are stupid. Go pray, sheep.

  • SERIOUSLY. Does anyone understand the difference between a flow system where a CONSTANT force is APPLIED and a closed system where the force is only due to the brownian motion of the molecules of water? Of course when you apply a force the pressure will change due to a changed nozzle size P = F/A HOWEVER for a closed system the Force per unit area is Constant so the nozzle size is irrelevant as TFoot demonstrate. OMG retake GCSE physics please.

  • This is just silly. Thunderfoot demonstrated using a gravity fed system and your comparing it to a pump/pressure fed system. Nice LOLGIC

  • oh my... spoonfed by NF? wow, how ridiculous... yes, spoonfed... It clearly shows that you either misinterpreted the two formulas... or you just dont know the difference... shame, not that you didnt know, but that you went out of your way to re-post a video which is clearly wrong or deceptive.

    I would take this down if I were you.. but hey, do your thing.

  • wow. this is still up after the intellectual beat down he gave you?!

  • Thunderfoot seems to be saying that one jet will not flow further in space (distance) than the other. And he is right. Only he mistakenly used the word 'velocity' (speed) instead of distance. The one with the larger hole flows faster, but not further. This is due to the fact that the pressure is not constant- as the height of the water decreases, so does the pressure. So as since the pressure decreases faster in the bottle with larger hole, the distance of flow of both remain even. Try it!

  • Does it occur to anyone that the argument here is over some ignoramus' delusional nonsense?

  • You will find numerous Atheists with a thorough knowledge of the bible, church history and religious philosophy... who studied at renowned learning institutions (even Jesuit) ... who can more than ably speak to the flaws and inconsistencies of organized religion's assault on the scientific method. But it seems like every time I read or watch a religious apologist try to use science against science they make a complete ass of themselves. If God gave you humility, you gave yourself humiliation.

  • Wow, just wow. I mean holy shit. Wow.

  • You still have this embarassment of a video up. Here, I'll do the first semester physics for you. To calculate the height of the water column: Force up = Force down. FU is Surface Area * Pressure. FD is Mass of water * gravity. Mass of water is Volume * density or Surface Area * Height * density. And there you have Surface Area as a linear factor on both sides of the equation. It cancels out. It does not matter. It increases force up and force down equally. Now apologize and bugger off.

  • Completely different system. Thunderfoot's system (and the one neph described in your water shooting out of the earth) are ones with a given pressure. The fire hose system does not. Not by a long shot. The pressure (and hence velocity) changes in this system to maintain flow rate.

  • The trouble is DebateCrusher, Nephlimfree censors literally everything. If you have a decent argument, you shouldnt have to censor what people write in a debate. I mearly asked Neph whether he had a degree, Just like that I was blocked!

    Why block me for asking such a simple question? Perhaps you could ask him that.

  • Those people just need to use buckets. Don't build anything that has to do with velocity PLEASE!

  • Changing to a smaller nozzle tip will increase nozzle velocity / pressure!

    Changing to a larger nozzle tip will decrease nozzle velocity / pressure!

    The inverse relationship between velocity and nozzle size simply means that when one increases, the other decreases and vice versa. DER! Do you even need an experiment for that?

  • this should be put on why people laugh at creationist.

  • Hi, I am currently writing a books on pump and valve mechanics. Sorry, Thunderf00t was dead on and Nephilimfree was way wrong.

  • NF fails again to understand the disparity, and so have you, "DebateCrusher". You fail physics. Bye

  • just because debatecrusher doesn't understand what thunderf00t was trying to teach doesn't mean thunderf00t is wrong. People see what they want to see. Stupidity makes my head hurt. Peace.

  • Neph makes a video copying your style, then you copy his video to make this one. There's some beautiful symmetry here.

  • *by* merely changing the hole size....etc.

    your opinion about length of water is poor evidence, since you're merely 'looking' without any precision in the measurements.

    the 'Gravity' Fed water system is LIMITED to the Weight of the Water Volume, thus you CANNOT Increase Velocity by Reducing the hole/nozel size...this can Only occur in a Continuous Flow system, such as a hose or alike.

  • DebateCrusher > with all due respect, NephillimFree has blundered here and so have you for supporting his Incorrect analysis of the experiment that TF conducted.

    Don't let your pride get in the way of Truth.

    NephillimFree's application of that information was Incorrect with respect to TF demonstration because TF used a 'Constant Pressure' system and Not a 'Constant Flow' system.

    take the video down, it's simply wrong and embarrassing.

  • @EvolutionLIE - with all due respect you're wrong. How so? Because a barrel if big enough is a relatively constant pressure system.

  • @DebateRobo .. i'm said the velocity of the expelled fluid is the SAME for Both Nozels ie. big and small nozels because of the particular system.

    this video is describing the change in velocity of the fluid in a 'constant flow' system which is not relevant to the 'thunderf00t' demonstration. hence, i said the video information is wrong.

  • @DebateCrusher ... the simple proof that what 'nephillimfree' said is incorrect, in particular, the statements that a smaller hole/nozel Increases Velocity is simply Untrue.

    What you are suggesting is that be merely changing the hole size you can Increase the Velocity thus Pressue in a Gravity Fed system (ie. as described by TF).

    If this Were True,you'd have a "Free Energy" Discovery !

    Fact Is, Reducing Nozel size ONLY INcreases Velocity, thus Pressure in a Continuous Flow System ie.hose

  • @DebateCrusher

    Do you have this demonstration? - I'd love to see it. TF00t is supported by textbooks and mathematical models which correctly predict the results when I attempted the experiment. The 'Trick' he pulled appears to be called 'education', and I'm always willing to learn if you've found some way of debunking the physics I've spent years learning.

  • @DebateCrusher You really think a constant volume (with pressure being dynamic) and constant pressure (with volume being dynamic) are effectively that same type of systems in terms of outputs? I bet you didn't learn that one in an introductory physics class at college. Or high school.

  • @DebateCrusher Ok, for the sake of argument: the bottles have different nozzle velocities. Now PLEASE use this to prove god and/or a flood on the fucking moon!

  • @DebateCrusher Go on Debate crusher, Im keen for you to prove the very foundations of physics wrong, obviously you can't.

  • GT35R is Correct "debatecrusher"....the equations and the references are relevant to a 'constant flow rate' system and Not a 'constant pressure system' as described by TF.

    changing the nozel/hole size Effects the flow rate in a 'Constant Pressure system' however it does Not increase or decrease the Velocity of the flow.

    the velocity is increased in a 'constant flow rate' system when the nozel is reduced in size, but this is Not what TF demonstrated.

    with all due respect remove the video

  • Once all is said and done you have a fundamental issue here. The energy needed to eject the water to the required height of velocity simply is not there. Nozzle size can not compensate for the fact that the energy does not suffice for the job needed. Not to mention this is a constant pressure system so the nozzle size should not make a difference

  • Comment removed

  • does stuttering change the velocity of his fallacies?

  • Well it's nice to see you again. Were have you been the last couple of months?

  • Can somebody tell me why we are trying to debate water landing on the moon from earth? what does this have to do with creation vs unguided evolution. ?

  • @weseyedwalk - I'm not arguing whether or not water can land on the moon. I featured this video because it shows that TF doesn't know science.

  • @DebateRobo

    Actually he does no physics. In a constant pressure system the per area pressure is the same. In other words your small or larger opening insures same pressure and since the opening determines the amount of fluid flowing out (in a constant pressure system) the Pressure/Area of opening ensures that the Force/ units of mass of water will be the same regardless of nozzle size.

    He is also talking about an ideal system. Regardless the nozzle size does not effect the height of water

  • @GT35R

    You'll have to forgive me for a moment. In Thunderf00t's demonstration, is the puncture in the water-bottle supposed to be considered the nozzle, or is the uncapped hole supposed to be?

  • @Ephemerance

    The puncture

  • @GT35R

    So Thunderf00t was incorrect in his demonstration?

  • Comment removed

  • @EvolutionLIE

    "clearly you don't comprehend the equation to ask such a question."

    You're partly right. I didn't understand what Thunderf00t was trying to convey with his demonstration. I was looking for clarification.

    "thunderf00t's an idiot"

    I think egocentric bully is the apt description - but that's beside the point.

  • @EvolutionLIE

    No, the froze does not remain the same..it scales down because you just decreased the area. In this system the force is perpendicular to the container. You remove half the area, you remove half the force hence keeping pressure the same. You clearly do not know what you are talking about. Are you telling me I can make ultra cheap industrial water cutting instruments by just putting a tiny nozzle on my gardening hose?

    Did you even take college physics? others ud kno beter

  • Comment removed

  • @EvolutionLIE

    Most of the force is acting perpendicular to the container. Only the force that affect the area of the opening effects the velocity of expulsion; in this expample the force/area / unit of water is the same regardless of the opening. Thus same velocity.

    If the force was constant, regardless of opening, then you would see similar flow rates in the two holes... but you don't. The larger hole empties faster. More force, more water to expel, same velocity.

  • @GT35R ... you're right

  • @EvolutionLIE reads like your just telling him he is right, to make him stop replying to you

  • @Toudiyama - Thunderfoot hasn't been responding to many of his critics on many issues. It's just that one gets the feeling that TF really has no arguments to argue.

  • @EvolutionLIE

    It really does not matter if I was right or wrong about nozzle size. The problem with this proposal is that the amount of energy needed to propel the water just is not there. Nozzle size can never make up for the insufficient energy.

  • @GT35R - I pointed out this video not to point out anything about propelling water through outerspace, but to show that TF didn't know his physics. And this video certainly did the job.

  • @DebateRobo

    No, TF was right. Nozzle size is not a factor in this circumstance.

  • @GT35R - Oh? the math equation proves that nozzle size does matter.

  • @GT35R ..that's true.

  • @weseyedwalk neph is stating that this provides proof that the flood is in fact possible so it really has nothing to do with creation or evolution BUT does involve an event in the Bible

  • OMFSM TF demonstrates what he is saying, and nephy tries to refute science by picking from article by a retired fireman those thing that when taken out of context seem to concur with him, amd you think TF should make a rebuttal

    let Nephilimfree first DEMONSTRATE that what he says can actually happen

    Misinterpreting some java animation is not demonstrating

    You just crushed the debate by showing not nrphy nor you do not undersdtand science

  • @Toudiyama - actually that's false. TF didn't demonstrate anything. He didn't have a good view of the bottles so you couldn't actually see how far the streams were traveling.

  • @DebateRobo other have done simular experiment and all show the same results

    nephy has never ever done any experiment period

  • Comment removed

  • @Toudiyama - You must be crazy. TF didn't demonstrate anything. The view of the bottles wasn't good enough.

  • @Toudiyama - actually it doesn't matter if the man was retired or not. Because he gave the math equations to determine that nozzle, contrary to what TA thinks, does matter.

  • @DebateRobo in a constant flow system which can not be used for a consyant pressure system like nephy.s

  • @sweatytoothmadman who are you people?

  • Sorry I didn't really say, I mean Nephys little fan base.

  • @sweatytoothmadman then I hit the no spam button right

  • The energy just is not there to propel the water that high. It is as simple as thought. Nozzle size will never make up for the lack of energy

  • @GT35R - not trying to argue that water will leave that high. The point in my bringing this video to mirror is just to prove that a nozzle size does matter and that TF doesn't know physics. 

  • @DebateRobo people have told him (NF) that that does not apply to a constant pressure system, this somehow doesn't get into nephy's thick skull and therefore he come up with a constant flow system and thinks he can apply this to his lunar bukake idea

    And this person calls others unifomitationist

  • Comment removed

  • @EvolutionLIE Plumbing isn't a constant pressure system. If it were, you couldn't get better water pressure by using narrower pipes, because...eh hem...the pressure would be constant!

  • Comment removed

  • Comment removed

  • @EvolutionLIE So, then you do believe they will drain at the same rate.

    I vs. V is a great analogy! If you had a constant current source (constant flow rate), you could continue to attach resistors in series and the current through them would always be the same. If you had a battery, a constant voltage source (constant pressure), the current would change with each resistor.

  • Comment removed

  • Comment removed

  • @EvolutionLIE So, you think "increases" is a good word to describe the behavior of something that is constant?

  • Comment removed

  • OMG are you kidding me? Do you understand the difference between a constant pressure system and a constant flow system? In constant flow (like a fire truck) systems the nozzle size will make a difference otherwise it wont. Have any of you guys who promote neph taken any physics in your life?

    If it was as easy as just changing the nozzle size than we could have cheap industrial strength water cutting instruments. You guys expect nozzle size to violate conservation of energy?

  • still waiting for you to crush a debate. Besides there are several issues with Nephs arguement beyond what has been stated. 1 he has yet to demonstrate in math how much pressure would be needed to get water to escape velocity.

  • @nessik13

    the 2nd problem is Volume. For the Earth to be completely flooded we would need roughly 3x the volume of water then is present in the ocean to reach the highest peak on earth. If neph says this water was under the earth then was the earth larger in volume prior to the flood? there was enough water under the surface to flood the entire world , Make craters on the moon and all the asteroids?

  • @nessik13

    Really supporting neph is not helping your crushing reputation.

  • @nessik13 - I don't support NephilimFree. In fact we had a bad exchange in pms early on. And I have never seen all his videos. I just posted this video because TF never answered it but just put out a personal attack video about aliens and NF's prayer life. I support ideas. If TF had a good idea I would support it. Doesn't matter who the person is. I do what I want. I'm not peer pressure oriented.

  • What I would like to see from Nephilimfree is the math of how much pressure was needed to eject water onto the moon and how much would have been on the earth in the first place. If he wants the scientific community to take him seriously, then he should do some math, not simply quote an incredible simple math equation for 5 minutes straight.

    jeesh....

  • @orge121 I'd like to see him do any math.

  • I have tried Tf00ts experiment using one bottle with two different size holes, the smaller je goes further,so as far as nozzle velocity goes, Neph may be right. BUT, if you think that this an anyway supports Nephs idiotic theory that water squirted out of the earth and landed on the moon then you're just as much a fantasist as him.

    You may think this discredits Tf00t, and he may indeed be wrong on this, but at least he isn't wrong EVERYTIME like Neph.

  • TF and many others have answered all of Neph's inane arguments, are you too lazy to view those videos?

  • don't tell me you are taking nephi's side here? he is CREARLY in the wrong (if you want, I can explain it pretty well too).
