What is the total power requirement for a rig, assuming the following functions are to be carried simultaneously: Hoisting: Maximum weight of 2,000,000 lbf, hoisted at 93 ft/min on 14 lines. The drawworks' efficiency (output/input power ratio) is 85%. Circulating: Two pumps capable of pumping at 550 gpm at 5,000 psi discharge pressure differential. The pump-volumetric efficiency is 90% with its mechanical efficiency at 90% also. Rotating: Maximum applied torque of 20,000 lbf at 120 RPM. The power-transmission efficiency is 90%. Miscellaneous power of lights, etc. is 1,000 hp
