The 36¾ -in pump of the figure below is to pump 20,000 gpm of water at 1,170 rpm from a reservoir whose surface is at atmospheric pressure (i.e. 14.7 psia). a) If head loss from the reservoir to the pump inlet is 6 ft, where should the pump inlet be placed to avoid cavitation for water. The vapor pressure of water at 60°F is 0.26 psi. b) Determine the required brake horsepower. c) The water is to be transported in an 80 cm pipe, and the engineer would like to measure the flow rate downstream of the pump using an orifice meter. What should be the orifice meter diameter if the pressure differential across it, is to be fixed at 1 m of mercury (density = 13,600 kg/m³).
