A certain 15-Kw pump running at 1600 rpm has an inlet diameter of 20cm and the discharge line is 12 cm in diameter. The output from th pump is 2800 liters/min of 20C and the centerline of the pump discharge is 1.5 meter above the centerline of the intake pipe. Determine the efficiency of pump. Please show complete solutions and formulas used. Show schematic diagram too.
