Answer:
Step-by-step explanation:
Volume of water in the swimming pool
= 25 x 11 x 3.1
= 852.5 m³
mass of water in the pool
= volume x density of water
m = 852.5 x 10³ kg
We shall consider the height H by which the centre of mass of the water-body is increased to lift the water .
H = 3.1 / 2 = 1.55 m
Work done in pumping the water out of pool
mgH ,
= 852.5 x 10³ x 9.8 x 1.55
= 13 x 10⁶ J
