Question

a 2kw motor is used to pump water through a height of 15m.The amount of water lifted per minute is.​

Answer 1

Explanation:

Power of pump=2kW=2000W

Time(t)=60s

Height(h)=15 m

We know,

Power=work done per unit time

Work done=mgh

=m×15×15

=225m

Power= 225m/t

2000=225m/60

m= 533.33kg

Hence,pump can raise 533.33kg water per minute up to 15 m height.
