The seawolf class nuclear submarines have a crush depth of approximately d = 745 m. the density of seawater is ρ = 1.03×103 kg/m3. atmospheric pressure is p0 = 1.01×105 pa.
find the inward force of the water, in newtons, at crush depth on a circular porthole with a radius of r = 0.11 m.
if the interior of the submarine is kept at atmospheric pressure, what will be the magnitude of the net force on the porthole, in newtons?
