Determine the kilovolt-ampere load on a generator for powering a crude oil pump if 

(1) The pumping rate at discharge manifold is 5000 m³/h against 100-m pressure head, 

(2) The pump pressure head to manifold pipeline is 20 m, and 

(3) The pump’s internal pressure drop is equivalent to the 10-m head of the fluid. Assume the pump efficiency to be 88%, motor efficiency 95%, motor power factor 90%, and oil specific gravity 0.85.
