Determine the pressure exerted on the surface of a submarine cruising $225\mathrm{ft}$ below the free surface of the sea. Assume that the barometric pressure is $14.7\mathrm{psia}$ and the specific gravity of seawater is 1.03 . The density of water at $32^{?}\mathrm{F}$ is $62.4\mathrm{lbm}/{\mathrm{ft}}^3$. The pressure exerted on the surface of the submarine is psia.
