Question

A water pumps lifts 18*10³ litre of water to a height of 30 m in one hour. If the efficiency of pump is 75% of power of pump is [ g = 10 m/s²]

Answer 1

There is a calculation to find the power consumption of a water pump. A typical water pump's wattage can vary between 250 watts to 1,100 watts. Take the wattage of the specific water pump and multiply it times how many hours a day it runs. Then, multiply it by how many days a year it runs, and divide by 1000.

Answer 2

Volume =18*10^3 l

Density =mass/volume

Mass=18*10^6kg

P=W\t

P=mgh/t

P=18*10^6*10*30/60*60

P=1.5MW

If efficiency =75%

P=75/100*1.5*10^6

P=1125*10^3

P=1125KW
