For Single -acting pump \ \

Number of Cylinders n = 3 \ \

Piston diameter d = 171 mm \ \

d = 171/1000 m = 0.171 m \ \

Stroke length s = 300 mm \ \

s = 300/1000 = 0.3 m \ \

Speed RPM = 230 r/min \ \

Slip = 16% = 0.16 \ \

Cross sectional area of piston A = (¼)πd² \ \

A = (¼)π(0.171)² \ \

A = 0.022954 \ \

Volume of Water discharge D = (A×s×n×RPM)/231 \ \

D = (0.022954×0.3×3×230)/231 \ \

D = 0.02 Gallons per minute \ \

1 Gallons per minute = 3.78541 Litres/minute. \ \

D = 3.78541×0.02 \ \

D = 0.07786 Litres/minute. \ \

The volume of water delivered is 0.07786 Litres/minute. \ \
