The current conditions for a centrifugal water pump are as follows:
Pump suction pressure = 140 psia
Pump suction temperature = 300°F
The pump requires a net positive suction head (NPSH) of 150 feet for pumping water at 300°F.
Which one of the following is the lowest listed pump suction pressure that will provide the required NPSH for the current pump suction temperature?
A. 132 psia
B. 128 psia
C. 73 psia
D. 67 psia
