What is the correct way to calculate the efficiency of a heat exchanger?
Effectiveness using $\epsilon = \frac{q_{act}}{q_{max}}$ seems to be most general. It assumes comparing 2 cases and I would choose comparing cases where inlet temperatures and flowrates are fixed for ...

What is the correct way to calculate the efficiency of a heat exchanger?
A good measure I think for what you need is Tout_Coldside/Tin_Hotside if you are trying to heat a cold fluid. Where if the Tout were equal to Tin_hotside then you would have a "100%" ...

Calculating cooling required in electrical panel box
Thanks all. I was able to find a couple of "rules of thumb" responses and averaged the outcomes from them, choosing a conservative number. I then made an hourly heat flow table to show how ...
