pump is to deliver water from an underground tank against a static head of 40m. The suction pipe 50m long and is of 25 cm diameter with Darcy-weisbach friction factor, f = 0.02. The delivery pipe of 20 cm diameter, 16m long and has f = 0.022. The pump characteristics can be expressed as: = 100-6000Q2 Where, H = Pump head in meters. P Q = Discharge in m³/sec. Calculate the head and discharge of the pump.

3) A centrifugal pump delivers water between two reservoirs with a 300 ft. elevation difference (Az). The 12-in diameter suction pipe (f1= 0.020) is 100 ft. long (L1) and the 10-in diameter discharge pipe (f2= 0.026) is 5000 ft. long (L2). The pump has a performance curve defined by the equation: h, = 375 - Q² where h, is the pump head in feet and Q is the discharge in ft/s. a) Calculate the discharge, Q. b) Calculate the NPSHA. Assume standard atmospheric conditions, 60°F water, and a pump elevation 8 ft. above the lower reservoir Az D, L2 2 D, Ly. ft LOM
