If an expansion tank were pressurized to 15 psig when installed,and the pump generates 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 occurs when the pressure generated by the pump is equal to the initial pressurization of the expansion tank. In this case, the expansion tank was pressurized to 15 psig, so when the pump generates a pressure difference of 20 psig, the point of no pressure change would occur at a pressure of 15 psig. Therefore, the answer is B) 15.
