Extracted text: 2.2-2b. Pressure in a Spherical Tank (Revised). Suppose that the spherical tank in the previous problem (2.2-2a) is submerged at the bottom of a pool of water that is 20 ft deep. Assuming that the oil and water are immiscible and that there is no pressure difference across the tank structure, calculate the pressure in psia and kN/m² at the bottom of the oil tank located at the bottom of the pool.
