Answer #1

Depth at which pressure is to be determine,

Density of seawater,

Absolute pressure of sea water at this depth-

Force exerted on the porthhole frame by this pressure-

Put P=8851046.4Pa, d=59cm=0.59m

So the submarine parthhole frame must exert same amount of force in opposite direction to counterbalance the force.
