Question

Double-acting duplex pump has 8.5 [in] liners, 2.5 [in] rods and 16 [in] stroke. Find pump factor [bbl/cycle], pumping speed (cycles/min), and the horse power drawn by the pump, if 10 minutes of pumping at 2000 psig required to lower the mud level in the suction pit (16 by 16 ft) isolated from the return mud flow by 2 ft. (Asssume 90% volumetric efficiency).
