Water data:
Sea water pressure = depth in feet x .445
Fresh water pressure = depth in feet x .432
Average sea water density = .037012 lb / cu. / in.
Average fresh water density = .036127 lb / cu / in.

Quick and easy dynamic pressure calculation:
Dynamic pressure in standard atmosphere = V(MPH)^2 / 391 = pounds per square foot
Dynamic pressure in sea water = V(MPH)^2 / .465 = pounds per square foot
