A diver in a rigid spacesuit can dive to the bottom of 250 m, and an experienced diver – to 20 m. Determine the water pressure in the sea at these depths.
h1 = 250 m.
h2 = 20 m.
g = 9.8 m / s2.
ρ = 1030 kg / m3.
P1 -?
P2 -?
The hydrostatic pressure of the liquid is determined by the formula: P = ρ * g * h. Where ρ is the density of the fluid, g is the acceleration of gravity, h is the height of the fluid, in our case, the depth.
The density of seawater is ρ = 1030 kg / m3.
P1 = ρ * g * h1.
P1 = 1030 kg / m3 * 9.8 m / s2 * 250 m = 2523500 Pa.
P2 = ρ * g * h2.
P2 = 1030 kg / m3 * 9.8 m / s2 * 20 m = 201880 Pa.
Answer: a diver in a spacesuit is exposed to water pressure P1 = 2523500 Pa, a diver P2 = 201880 Pa.
