The heat from the pump cannot possibly affect the calorimetry, for the reasons I stated here and in the report. > I do not have the same report that you have identifying the pump > specifications on page 24.

This is shown in Fig. 19. Heat is measured based on the difference shown with the purple arrow in Fig. 7. The bottom of that arrow points to the temperature of the water which already includes heat from the pump. > In any case a good description of "baseline" conditions is warranted. > What is the matter with the description on p. 24? It does not seem complicated to me. - Jed
