I confused the issue a little here.

Dennis meant that you do not need to measure the inlet and outlet
temperatures to conduct flow calorimetry. You can simply circulate all the
water from a large body like a bath, going from bath to cell, and splosh
back into the bath. You then observe the terminal temperature of the bath,
comparing it to another bath with another heater. It is a giant
isoperibolic calorimeter at a moderate temperature. (Whereas the present
arrangement is a small, hot isoperibolic calorimeter.)

I meant that you do not need to worry about flow rates with the present
method. There is no flow involved. I also meant that you do not need to
worry about the airflow cooling the cell because you can look it up in a
book. Granted, it is not very accurate but HVAC engineers have been doing
this sort of thing for a long time, so it is reliable.
