A centrifugal pump as shown in Figure below has a 100 mm diameter suction pipe and a 75 mm diameter delivery pipe. When discharging 15 L/s of water, the inlet water mercury manometer with one side exposed to the atmosphere recorded a vacuum deflection of 198 mm of Hg; the mercury level on the suction side was 100 mm below the pipe centerline. The delivery pressure gauge, 200 mm above the pump inlet, recorded a pressure of 94.666 Kpa. The measured input power was 3.2 kW. Calculate the head added by the pump in m.
