Question

the power of motor pump is 2kw. how much water per minute can the pump raise to a height of 10m?(given g=10ms-2)​

Answer 1

Answer:

1200 kg

Explanation:

time =60 second

2KW=2000W

height=10meter

then,we suppose that mass of water in per minute is M.

power=work done per unit time

W=mgh

W=M*10*10

W=100M

then,

2000= 100M/60

M=12 kg
