Question

A water pump can raise 500 litre of water from a depth of 30 m to a water tank at a height
of 20 m in 5 min. Find the power of the pump in watt and in horse power.​

Answer 1

Answer:

here's your answer

Explanation:

Mass of water lifted, m=Vρ

where V is Volume of water and ρ is density of water

V=500l=0.5m

3

and ρ=1000kg/m

3

m=0.5×1000=500 kg

h=50 m

Work done in moving water to a height 50m is W=mgh

W=500×9.8×50 J

P=

t

W

=

98

500×50×9.8

=2500 W=2.5 kW
