I thought that in a closed system there was no head pressure. If the system is
pressurized, there is system pressure, but still no head pressure. The closed loop
cancels everything out.
Just wonderin' .... Jim S.
Yes, I do think it would account for errors in the test. Head pressures on
pumps are a big factor in sizing pumps & motors in industry.
