And . . . Here is definitive proof of what I say. It happens that Mizuno sent me a large data set which includes about 35 hours where nothing was happening. He left the computer running, and he left the heating on so the ambient temperature was reasonably stable. I see it was especially stable during the last 28 hours. The pump was also running all this time. Here are the cooling water temperatures for the first 14 hours and the second 14 hours:
First 14: Average 17.85°C, min 17.64°C, max 18.08°C Last 14: Average 17.81°C, min 17.65°C, max 18.10°C There is no difference. The pump did not change the temperature. Using the adiabatic method of calorimetry we see *zero heat* in this data set. There is NO INCREASE in the water temperature even though the pump is adding heat the whole time. It has reached the terminal temperature for the pump input. Really, people should stop debating this. The pump cannot possibly affect this method of calorimetry. - Jed
