A single acting reciprocating pump drawing water from a sump and delivering to a tank has a cylinder of diameter of 100 mm and a stroke length of 200 mm. The water level in the sump is 4.5 m below the centre line of the pump and in the tank water level is 13 m above the pump centre. The diameter and length of the suction pump are 40 mm and 5 m while that of delivery pipe the diameter and length are 30 mm and 20 m, respectively. If atmospheric pressure head is 762 mm of mercury and the separation occurs at 2.5 m of water absolute, then find the maximum speed of the pump.
