Prob. 3. Figure P2 shows a pump and piping system. The pump is to move ethylene glycol at a flow rate of 50 gpm. Follow the suggested design procedure and select a pump for the case when Z1 = 4 ft and Z2 = 12 ft. COA A Notes: A Globe valves (2 of them) B Union fittings (4 with 2 not shown) C Plate welded to tank to suppress air entrainment in pump inlet D 5-90 Elbows 2-45 Elbows The pipe is all wrought iron, with threaded fittings, schedule 40. Pipe lengths total 116 ft. The fluid is ethylene glycol. The flow rate required is 50 gpm. Total inlet pipe length from tank to pump is 4 ft. Z1 4 ft and Z2 = 12 ft.
