Alright, I got it now! thanks.
I have another question though.
The correction factors, whichs exists for all heat exchangers.How are they determined? Is it experimentally or proven science?
Thanks!
Alright!
i know the part that the heat resistance film is getting thinner as the fluid is more turbelent, which is more flow rate.
I retried some fittings, and thought about a very logic function and found a new, actually more believable function of
U=a*M/(M+b). So if the flow rate is o, you...
I did a study on how good the HE could cool by changing both the volume rate.
What I experimentally found out is that
Q = U A ΔTLM
the U (overall heat transfer coefficient) can be written in a function of one of the fluidums mass rate when I keep the other fluidum's mass rate constant:
so...
