Question

A Water Falls is nearly 20 m high 2000 tonnes of water falls
from it in a minute Calculate the equivalent power if all this
energy can be utilized Take g = 10 m s -2

Dear Student ,

Given that:

Height=20 m

Mass of water=2000 tonnes=(2000 x 1000)kg

Acceleration due to gravity,g=10 m/s2

Now potential energy=mgh

=(2000 x 1000) x 10 x 20
=4×108J

Power=4×108J / 1 min

=4×108J/60sec
