Fluid Machinery Problems

A single acting reciprocating pump has a cylinder bore 90 mm and a stroke of 180 mm. Water is to be drawn from a sump 3 m below the axis of the cylinder, through a 50 mm diameter and 6 m long pipe. The pump delivers the water to a tank at a height of 8 m through a 25 m long, 50 mm diameter pipe. If separation occurs at 0.0765 N/mm2 below the atmospheric pressure and the barometer reads 760 mm of mercury, find the maximum speed at which the pump can run?
