Using standard gear, a scuba diver can go to a depth of 130ft.What is the water pressure on him at that depth?

Water weighs 62.4 Lb/ft^3
at 130 ft the column of water above him weighs:
130*62.4=8112 lb
That is aso the presure acting per square foot. The pressure per square inch is:
(8112 lb/ft^2)/(144 in^2/ft^2) = 56.33 psi.

    1 atmosphere added per 33.9 feet of water, so 4.8 atmospheres or 70.56 PSI
