2 - If you plan to include inlet vs outlet temperature differences in your equations, do so but properly. You must take the logarithmic (ln) sum of those temperatures.
|
Heating up a specific amount of water with a constant heatload produces a LINEAR rise in temp. If you think you somewhat trick that into beeing logarithmic I suggest you restudy your thermodynamics.

I'll save you a lot of work and headaches by telling you higher flow leads to better results (higher transfer rates).

I didn't make any contradictary statement that I can recall.
And please stop asuming all others in theese foums to be total morons. There are actually alot of intelligent people here. That doesn't get a headache over a few differential equations like you do.
Some of us actually work with them all day long and are happy and smiling anyway.

You're trying to solve something by equation.

Not trying to solve a problem. I'm trying to redirect our joint efforts on what matters and kill a few general "thinkerrors" that that a few persons do.

Higher flow is better for watercooling whether it's in a nuclear powerplant, a car, or a computer

Again I newer made a contradicory statment.
I stated that the tempdiff as a function of flow has a small impact on the cooling.
Higher flow is better but because of other factors.
NOT because it makes a lesser tempdiff in the WB.
