Question

a 1 km moter is used to pump up water through water through a height of 10 meter calculate the amount of water lifted per minute​

Answer 1

Answer:

Power of pump=2kW=2000W

Time(t)=60s

Height(h)=10 m

g=10ms

−2

We know,

Power=work done per unit time

Work done=mgh

=m×10×10

=100m

Power=

t

100m

2000=

60s

100m

m=1200 kg

Hence,pump can raise 1200 kg water per minute up to 10 m height.
