[Vo]:Heat from the pump would not be a problem even if we could detect it

Some people are still confused about the input power from the pump in Mizuno’s calorimetry. Let me point out two things about this: 1. While there has to be some heat from the pump, with this configuration, that heat is too small and too close to the noise to be detected with this equipment.

Jed, is it possible to calculate the amount of power that is being added to the water by looking at the system? I assume that the water is not moving just prior to being accelerated to finally reach the speed that it is moving inside the pipe. That may allow you to calculate the kinetic

Here is some more info on the pump, that Mizuno just sent me: IWAKI magnet pump, MD-6K-N Max capacity: 8/9 ℓ/min Max head: 1.0/1.4 100V 12W/60Hz, 12W/50Hz He plugged it into the WattChecker which shows it is drawing 10.8 W. (I thought it was 5 W just by feel. Not a bad guess!) Based on the
