A single-acting triplex pump with 8-in liners and 20-in stroke length has a volumetric efficiency of 90%. The pump pressure is 2000 psi. a. Obtain the minimum required pump speed in (strokes/min) to pump at least 6000 gal drilling fluid down the wellbore in 8 minutes. (18 points) b. At the pump speed that you calculated from part a, calculate the energy efficiency of the pump (%), If the required electrical power input of the pump is 1000 KW. (1hp=0.7457KW) (12 points)
