7.16 Figure 7.21 shows a pump delivering 840 L/min of crude oil (sg = 0.85) from an underground storage drum to the first stage of a processing system. (a) If the total energy loss in the system is 4.2 N-m/N of oil flowing, calculate the power delivered by the pump. (b) If the energy loss in the suction pipe is 1.4 N-m/N of oil flowing, calculate the pressure at the pump inlet. Air at 825 kPa 1.5 m Flow 10 m Pump 3 m Suction pipe 2-in Schedule 40
