Question

a swimming pool of width 9m and length 24m is filled up with water to a depth of 3m.
Calculate the pressure on the bottom of the pool due to water(g=9.8m/s2)

Answer 1

29400 N/m².

Pressure: This is defined as the force acting normally per unit area.

From the question,

P = ρgh........................ Equation 1

Where P = pressure, ρ = density of water, g = acceleration due to gravity, h = height.

Given: h = 3 m.

Constant: g = 9.8 m/s², ρ = 1000 kg/m³

Substitute this values into equation 1

P = 100(9.8)(3)

P = 29400 N/m².
