Two oil containers are connected to each other through a differential manometer. The difference between the mercury levels in the two columns is 32 in. Determine the pressure difference between the two tanks. The densities of oil and mercury are 45 lbm/ft3 and 848 lbm/ft3 , respectively

In every exercise, you must highlight your main assumptions, highlight the given data and unknowns, draw a sketch, present your equations in full form, and specify the units in every step. A brief discussion of your findings is encouraged.
