Because of a break in a buried oil storage tank, ground water has leaked into the tank to the depth shown in Fig. P1.48. Determine the pressure at the oilwater interface and at the bottom of the tank, each in lbf/in.2 (gage). The densities of the water and oil are, respectively, 62 and 55, each in lb/ft3 . Let g 5 32.2 ft/s2 .
