I'm currently working on a model. One version uses
these formulae. I am not certain about them actually, but it does match what I have been generating myself, fairly well so I am accepting it for now.
The problem is, fitting theory with pHaestus' testing gives values for
h which are very high in my opinion. For the Cascade and MCW6000 we are talking values between 50,000 and 150,000W/m^2*C depending on flowrate. This feels wrong to me. But Cather has demonstrated numbers well over 100,000 in his testing so I don't quite know what to think. For the MCW5000 and #rotor blocks the numbers are in the region of 10,000-30,000, showing that they are a fundamentally different type of block.
Guesses all but somewhat grounded in the region between reality and theory.
