If the existing vapor pressure is subtracted from the indicated pressure at the pump suction, the remainder is the _______________.
AI Explanation
A) apparent net positive suction head is the correct answer.
The apparent net positive suction head (NPSH) is the difference between the indicated pressure at the pump suction and the existing vapor pressure. This value represents the available NPSH, which is a critical parameter in ensuring the pump operates without cavitation.
The other options are incorrect because:
B) Pump head refers to the total increase in pressure generated by the pump.
C) Discharge head is the pressure at the pump outlet.
D) Total suction head includes factors like friction losses, in addition to the existing vapor pressure.
