A tank 20 ft deep and 7 ft wide is layered with 8 ft of oil, 6 ft of water, and 4 ft of mercury as shown in the accompanying Figure. Assume all layers are at T = 50 °F. Find:
(a) Compute the hydrostatic pressure, in psi, at the bottom of each layer. Patm = 0 psi.
(b) Using the diagrams, compute the resultant pressure force, F, on the right-hand side of the tank.
(c) Compute the resultant center of pressure of the liquids on the right-hand side of the tank.
