Mineral oil is pumped through a horizontal pipe with a pump at the rate of 3800 m3 perday. The pipe is made of new steel with roughness 0.2 mm. The length of the pipe is 32 kmand its internal diameter is 219 mm. The pressure is equal at both ends of the pipe. Thepump efficiency is 0.65 and the efficiency of electromotor including mechanicaltransmission is 0.88. The oil density is 900 kg.m-3 and viscosity is 0.04 Pa.s. Calculate theconsumption of the electric energy consumed by the pump during 24 hours. Assume that byusing the pump the oil pressure at the input to the pipe is equal to that at the end.Result: Consumption of the electric energy by the pump is 6.16 MWh per day
