Step: 1

Given:
Length of swimming pool
Width of swimming pool
Height of swimming pool

Step: 2

Specific weight of water,
Area,

The distance from free surface of water to centroid of the wall:

Step: 3

(a)
Hydrostatic force on the wall:

Thus the hydrostatic force on each wall is

Step: 4

Distance of line of action from the ground:

Thus the distance of line of action from the ground is .

Step: 5

(b)
Hydrostatic force on the wall when the height of the pool is doubled:
