an electric pump of power life 4000 of water to a height of h in 30 min find the height
Answers
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.
