borewell HP calculation.

say water is being produced at 1800 litres per hour i.e. 1800 kg per hour. say the depth is 230 feet. If it has to be pumped 70 feet to the tank so total of 300 feet = 100 meters. so total amount being pumped is 1800 X 100 kg meters per hour. This is same as 3000 kg m per min. 1 HP = 4500 kg m. So 3000 kg m = 0.66 HP. Keeping any future yields (say double) we need 1.3 HP. Keeping machine inefficiency, friction loss, bend losses, non return valve losses and eddy currents into account, we need 1.5 HP.
