3. An occanographer is testing the acidity of the Atlantic oocan by placing a circular measuring device on the vertical face of the continental shelf. The measuring device has a radius of 1 meter and is placed so the top of the measuring device is exactly 125 meters below the surface. Calculate the hydrostatic force on the measuring device. Use 1024 kg/m2 for the density of the seawater in the Atlantic ocean, and 9.81m/s for the force of gravity. (15 points)

Answer 1

Hydrostatic force is give by :

F = Pressure x Area

  $=\rho\;g\;h\;A$

= 1024 x 9.81 x 125 x $\pi$ N

= 3.944 x 10⁶  N

F = 3.944 x 10⁶  N
