The design operating point of a centrifugal pump with a radial impeller is specified as follows: Speed = 2000 RPM, Actual Head, Ha = 200 ft, Flow Rate 50 gpm. %3D At the impeller outlet: radius, r2 = 6 in; b2 = 0.5 in, and the blade angle, 6b2= 60. Total shaft power 4 HP, and the derivative of actual head, Ha, with respect to flow rate Q, (dHa/dQ) = 8 ft/gpm. The volumetric efficiency due to leakage 0.92 %3D %3D Determine: a) The Slip Factor b) Hydraulic Efficiency c) Mechanical efficiency.
