1) The suction side of a pipe system consists of an 8-in diameter pipe with a friction factor of 0.0185 that is 250 ft long and 10 feet above the reservoir level. If the pump discharges 495 gpm under a total head of 100 ft at 40°F and there is an atmospheric pressure of 32.7 ft of water, what is the NPSH in feet?
