Determine the work done by the impeller per kg of water. (8) Explain the working of single acting reciprocating pump with a neat sketch. (5) A single acting reciprocating pump has piston diameter 12.5 cm, and stroke length 30 cm. The center of the pump is 4 m above the water level in the sump. The diameter and length of suction pipe are 7.5 cm and 7 m respectively. The separation occurs if the absolute pressure head in the cylinder during suction stroke falls below 2.5 m of water. Calculate the maximum speed at which the pump can run without separation. Take atmospheric pressure head as 10.3 m of water. (9) Make a note on closed loop servo system. (7) Explain the working of a hydraulic torque converter unit. (7)
