PQA Ep. 2: Water Cooling T-Lines & Multimeters (Part 1 of 2)

PQA (Petra's Questions & Answers): Episode 2, Water Cooling T-Lines & Multimeters.

In this episode, I end up running quite long (which is why it's a 2 part episode) but manage to cover the use of a T-Line in a PC water cooling system (pt.1) and the basics of using a multimeter (pt.2).

Part 2 of this episode can be found here: http://www.youtube.com/watch?v=FJU3qk6mJbU

@OreiZlatan Closed-loop cooling system performance is a lot more complicated than just thinking of how much time any given water molecule spends in one place. As it pertains to PC cooling, if you want to introduce restriction into the system, then do it in a useful way and add a nozzle at the inlet to a block. This will increase local coolant velocity and improve performance through crude jet impingement (waterblocks rely on targeted coolant turbulence to perform well).

[PTPetra]

@OreiZlatan In a closed loop in which the coolant flowrate is >0, coolant will spend roughly the same amount of time in the radiator regardless of flowrate during a given period of time. Think of it this way: 2 cars are on a 1 mile circle track, one car is traveling at 40mph, the other at 120mph. It takes 1 car 90sec. to lap the track & the other takes 30sec. If your radiator represents 1/4 of said track, both cars will spend 900sec. in that area in 1 hour.

@OreiZlatan Engine cooling systems are pressurized, high temperature systems that are designed to maintain a particular temperature range, not make things as cold as they can. The engine temperature increasing has more to do with the design of the water jacket than the "amount of time" water is spending in a radiator (think negative impact of transition from laminar flow to turbulent flow within the water jacket).

@OreiZlatan With a comment like that, I'm just going to assume that you're trolling. Then again, maybe you're not... a reduction in outlet diameter would increase the pressure drop across the block, which would reduce coolant flowrate, and result in an overall decrease in system performance. This has been proven both mathematically and through numerous controlled experiments. Note: I'm only talking about typical PC water cooling systems here.

Liquid cooling a PS3 is both unnecessary and difficult.

Petra you should help me liquid cool my PS3. pl0x

Can i get an old watercooling kit if I send a pre-paid shipping box? :P
