What pressure does a submarine at a depth of 50 m experience?

What pressure does a submarine at a depth of 50 m experience? What pressure force acts on the hatch in the boat if its area is 22 and the density of seawater is 1300 kg / m3.

h = 50 m.

S = 2 m2.

g = 9.8 m / s2.

ρ = 1030 kg / m3.

P -?

F -?

The hydrostatic pressure of the liquid is determined by the formula: P = ρ * g * h. Where ρ is the density of the liquid, g is the acceleration of gravity, h is the height of the liquid, in our case the depth.

P = 1030 kg / m3 * 9.8 m / s2 * 50 m = 504700 Pa.

Pressure P is the ratio of the force F to the area S on which it acts: P = F / S.

F = P * S.

F = 504700 Pa * 2 m2 = 1009400 N.

Answer: the pressure on the boat is P = 504700 Pa, the water presses on the hatch with a force of F = 1009400 N.
