A triplex mud pump having 6-in liners and 15-in strokes was operated at 3,300 psig and 60 cycles/min for 15 min with the suction pit isolated from the return mud flow. The mud level in the suction pit, which is 7 ft wide and 20 ft long, was measured to fall 42 in during this period. a) Compute the mud factor as gal/stroke, b) Compute the volumetric pump efficiency, c) Calculate hydraulic horsepower developed by the pump.
