A solution of ethanol is pumped to a vessel 25 m above a reference level through a 25 mm inside diameter steel pipe at a rate of 10 m3/h. The length of pipe is 30 m and contains two elbows with friction equivalent to 20 meters each. Compute the power requirement of a pump. Solution properties include density of 975 kg/m3 and viscosity of 4×10-4 PaS.
