Question

The density of the water in the lake is 1000 kg/m³ and the atmospheric pressure at the

surface is 1.0 x 105 Pa.
Calculate the total pressure 25m beneath the surface of the lake.

Answer 1

Answer:The pressure at a depth of 25m in water can be calculated using the formula:

P = ρgh

Where:

P = pressure

ρ = density of water = 1000 kg/m³

g = acceleration due to gravity = 9.81 m/s²

h = depth = 25m

Substituting the values, we get:

P = (1000 kg/m³)(9.81 m/s²)(25m) = 2.4525 x 10⁵ Pa

The total pressure 25m beneath the surface of the lake is 2.4525 x 10⁵ Pa.
