Harry,
I agree the energy utilized should be subtracted from the
output but how much of the pressure or flow rate is actually removed from the
system? - the differential measurements are only for temp but you should also
quantify the pressure/flow rate into the reactor and the pressure/flow rate out
of the reactor if you want to determine if any energy was added or subtracted -
otherwise the same pressure and flow are still potential - available for use
downstream. I am sure the portion of pressure/flow removed from the system is
only a small fraction. Maybe put the exiting water after measurement into same
diameter pipe as the source and measure with an identical flow rate meter?

Subject: EXTERNAL: Re: [Vo]:Pump power must be included
Whether or not the water flow is powered by the pump
or a waterfall, the kinetic energy of the flow may be a factor.
A lack of water movement may explain why some PF type cells failed to perform
in the past.
They depended on the fickle nature of convection to spring to life.

yes, good point Jones, the system input power includes the power to operate the
pump and the resistive heaters.
That is incorrect. Please review the messages I have posted. The input power
does not include the pump any more than it includes the overhead lights or an
oscilloscope. Heat generated before the inlet sensor or after the outlet sensor
is not measured.
