Determine the pressure exerted on a diver at 20 m below the free surface of the sea. Assume a barometric pressure of 101 kPa and a specific gravity of 1.03 for seawater.

Step 1:

To determine the pressure exerted on a diver at 20 m below the free surface of the sea.

The depth below the surface of the sea h = 20 m

Barometric pressure p0 = 101 kPa

Specific gravity of seawater SGSW = 1.03
