A pump can raise 900 liters of water per minute to a height of 50 meters caculate the h.p.(metric) of the pump.

Answer 1

Wt. = 900Liters * 1oz/0.03Liters = 30,000 Ozs. = 1875 Lbs./min.

Mass = 1875Lbs * 0.454kg/Lb. = 851.25 kg./min.

P = M*g*d/t = 851.25/60s * 9.8 * 50 = 6952 J/s = 6952 Watts.

h.p. = 6952/746 = 9.32.
