Nice to see that somebody acually took the time to read it :-)

I agree on the timeconsuming aspect of it all, but if you choose a small amount of water. Then it will go faster.

However I think you missed one of the points with this setup, or i explained it poorly.
So here is another try:
1* Since you calibrate each WB to get the certain K_pump for that particular WB/restriction then the differences that occur in the pump gets cancelled out. No flow measurement needed!.
If you decide to change the flow with a restriction the you must recalibrate.

2* As you see i can extrapolate the power the pump is adding to the system. By measuring the deltaT, the time and the amount of fluid. This calculation is also possible on the second measurement and gives the total power added to the water by the simulator and the pump. Subracting the total power with the pumps gives you the exact power that the WB recives and transports to the water. If you at the same time meassure U and I to the simulator (SIM) you can caculate the losses from the SIM to the secondary heatpaths.

3* If we would isolate the WB and SIM from the sourrundings with a box the the WB would collect heat/power from the hot air inside the box which it normally wouldn't and it would perform better than in a real world application.
However you are correct that there is no way to compensate for the differences in secondary heatpaths with this setup and a real CPU.



More comments/ideas/thoughts anyone.
