Goal: To calculate hydrostatic force and hydrostatic pressure on a submerged object.

Ex. Suppose a penny is lying 8 ft below the surface of a swimming pool. Find the pressure on the penny.

Find the hydrostatic pressure at the bottom of the tank.

a)

Find the hydrostatic force at the bottom of the tank.b)Find the hydrostatic force on the end that is 4 meters wide.

c)

Ex. Suppose a rectangular tank is 8 meters long, 4 meters wide, and 1.5 meters high. Also suppose that the tank is filled with a liquid of density 820 kg/m^3.
