Question

power of water pump is 2kw if g 10m/s the amount of water raise in one minute to height of 10m

Answer 1

p=mgh/t
pis given as 2kw=2000watt
g=10 m/s
h=10m
time =60 s
putting these values
2000=(m×10×10)/60
m=1200

Answer 2

Given,

Power = 2kw = 2000w , Height H = 10m , Time taken t = 60 seconds.

Now ,

Power = Energy/time = mgh/t

2ooo = m*10*10/60

We get m = 1200 kg

Therefore , the pump lifts 1200 kg or 1200 l of water to a height of 10m every minute.
