That is around about what I have measured too. If not a bit lower. I am almost certain that pHaestus is getting even lower than this in his setup. Practice perhaps.
h eff. Yes indeed Les, I am talking only about the effective coefficient.
As far as "The tc offset in the bp ~ 0.001 - 0.05..." goes, I have measured a value for copper of, from memory, 0.0245 ish C/W/mm*100mm^2. It should be 0.0255C/W/mm for a parallel heat channel with xsectiom 100mm. With spreading effects, lower?
Where oh where is that magic formula for effective "
h "? with the simple terms flowrate, surface area.... The dimensionless variables are blowing my neural circuits.
