A double acting reciprocating pump has a piston of 250 mm diameter and piston rod of 50 mm diameter, which is on one side of the piston only. Length of piston stroke is 380 mm and the speed of the crank moving the piston is 60 rpm. The suction and delivery heads are 5 m and 20 m respectively. Find the force required to work the piston during the inwards and outwards strokes. Determine the quantity of water in litres per minute raised by the pump and power required.
