Calling Ed Storms!
Please set Jed straight on this issue.
You do not need Ed. Ask anyone who has done flow calorimetry about this.
Better yet, build a flow calorimeter. I have built several and seen dozens.
He does not think that a large source of electrical power added to the
system needs to be accounted for.
It is NOT added to the system, for crying out loud. That is physically
impossible! There is no mechanism to add it, since the water is still
moving when it emerges from the machine, as fast as it was when it went
in. This is fundamental Newtonian physics. You cannot convert mechanical
action to heat unless you slow down or stop the body in motion.
There are two P-in points, one for the whole system and one for the
calorimetry.
What on earth is that suppose to mean?!? The "whole system" is the cell.
There is only 1 P-in point, right smack there where the inlet
thermocouple is located. Where do you suppose the other one is?!? Why
would you need another one? Heat added to the water before P-in cannot
be measured with this system. There is no "system" "for the calorimetry"
separate from the cell.
When they turn on the flow of water before they turn on the cell, the
heat balance remains at zero. No heat is detected. That is true whether
the pump pushing the water is in the room or whether it is in the
municipal reservoir 20 km away.
