A centrifugal pump draws water from a 38cm pipe from an open reservoir in which the water surface is 2.6m below the pump centerline and discharges through a 30cm pipe. At a point in the discharge 2.35m above the pump centerline a pressure gage reads 320 kPa gage. The discharge is 200Liters/sec, the head loss in the suction is 0.15m and in the discharge is 1.05m. Power input to the pump is 140hp. Determine the following: a. The total dynamic head in meters 36.923 41.527 39.188 b. The Water Power (WP) in kW 76.863 80.451 81.451 c.

A centrifugal pump is used to pump water (1000 kg/m³) to a height of 10m, the water splashes down back into the tank. The diameter of the impeller of the pump is 145 mm, the pump speed is 2900 rpm. The equation to calculate the flow V in the valve depending on the pressure drop differential pressure (dp) in the valve isV = 4 * sqrt (dp), whereas V is in m³/h and dp in bar. Please estimate the water flow.
