The interior of a submarine located at a depth of 45 meters is maintained at normal atmospheric conditions. Find the total force exerted on a 20 cm by 20 cm square window

Respuesta :

Answer:

P = ρ g H      pressure due to 45 m of water

P = 1000 kg/m^3 * 9.8 m/s^2 * 45 m^2 = 4.41E5 kg/s^2

P = 4.41E5 N/m^2      pressure in excess of atmosphere at surface

F = P * A = 4.41E5 N/m^2 * 1/5 m * 1/5 m = 17,160 N/m^2
