You work for a manufacturer of hydraulic presses and have been assigned the enviable task of analyzing the proposed piping system in the figure shown below. A pump moves hydraulic oil from a supply tank to the press. The press needs at least 20gpm to operate properly. The valve in the pump outlet line is to be used to reduce the flow rate if more than 30gpm is provided. The pipe sizes have already been selected, not based on a minimum cost analysis, but because "we have lots of these pipe sizes in stock". The inlet line to the pump is 2-nominal schedule 40 PVC, 2.5 m long. The outlet line from pump to press is 1 2 1 -nominal schedule 40PVC,6 m long. The pressure of the hydraulic oil delivered to the press must be 30psia. After being used in the press, the oil is discharged to an elevated tank at the top of the press. The return line from this tank to the supply tank is 12 m ling, and its diameter has not been selected, but it too should be made of PVC. The heights are H=6ft,h=8in., and d=12in. 1. Size the pump.
