If an expansion tank were pressurized to 15 psig when installed, and the pump generated a pressure difference of 20 psig, the point of no pressure change for the system would be __________.

Question

Quizplus · Accepted Answer

The point of no pressure change for the system is the pressure at which the expansion tank is pressurized. In this case, the expansion tank is pressurized to 15 psig, so the point of no pressure change is 15 psig. Any pressure difference above this point will result in an increase in pressure, and any pressure difference below this point will result in a decrease in pressure.
