The bathyscaphe dives to 3,652 m below the surface. The average density of seawater may be assumed to be 1,024 kg/m3. Approximate the bathyscaphe as a sphere of diameter 3.1 m. Atmospheric pressure at the ocean's surface is 101 kPa. Determine the net force, in kN, on the bathyscaphe's hull if the interior pressure is maintained at 120 kPa, for the comfort of the scientist inside. All pressures are specified in absolute. The thickness of the hull may be neglected.
