Fluids (part 7)

[TurbotortoiseStickle]

I'm at a paradox here. I've heard a theory of a possibility of compressed liquid core gas giants that emit no thermal energy. Can open space be so cold as to freeze liquids, compressing them as their gravity increases? If so, what prevents thermal generation? I could never understand that part.

Where is the horse??

[ElaM1NaTo]

Why is output velocity unequal to input velocity?

[92310CAMILLE]

@ElaM1NaTo because of area,remember the flow rate formula...V1A1=V2A2

[92310CAMILLE]

@92310CAMILLE where v is the velocity and a is area..

i always thought of him as a guy in his mid 40s or something, but Sal is young, his voice is very mature for his age.

what happends to the viscosity of water when pressure changes

[slmUSA]

Thank you!

[rotflmaopmpqxyz]

aaaaah velocity and volume are both represented by v. SO CONFUSING.

But you explain it very well. Thanks (:

the first video with 44 likes and NO DISLIKES!

AMAZED! :O

I don't think that's what actually happens. If you pour in the small opening, the water will just flow with constant velocity, as it doesn't have to fill the whole tube. If you pour from the large opening, it would rush out of the large opening if your flux is large enough. Anyway, it is a great video.

Really, very helpful

[farzero]

liquids are incompressable? that is insanely thought provoking to me. wow thanks.

[GoldAK47]

Makes sence you know what I'm saying... try to compress a bottle of water (with no air inside it)... as hard as you try it, you won't be able to compress the water.

[TheWestWind17]

to a certain point. for example water does compress in the ocean for example with increasing depth due to the enormous weight of the water overtop of it.

[pyVlad]

@farzero They're not actually incompressible... but it's a good approximation for most liquids we'll ever deal with.

[stycomass]

correct me if i;m wrong. the key assumption for the continuity equation is that the fluid is an ideal fluid, with no viscosity therefore no friction and incompressible. Laminar flow do have frictions between the fluid layers because of the no slip boundary conditions. I hope im right. :)

[joshua2mulder]

The equation of continuity requires no assumptions except that the density and velocity are continuum functions. That is, the flow may be either steady or unsteady, viscous or frictionless, compressible or incompressible. However, the equation does not allow for any source or sink singularities within the element. Hope this helps

[stycomass]

@joshua2mulder thanks...that;s true. I was playing around too much with the Laplace's equation... :)

glass is classified as an amorphus solid.

[loverofindia]

yeah, it's viscosity is so high it looks like a solid. I guess that's how glass is a solid AND a liquid: an amorphus solid

[quangster]

god bless you!!!!

[IamBored529]

@quangster I agree, God bless Sal

[volintine]

ohh good video
