Consider the flow situation illustrated in Figure P7.24. The oil has a specific gravity of 0.90.

(a) Suppose that water is flowing into the tank at exactly the same mass flowrate as that of the oil flowing out of the tank. In which direction, if at all, is air moving through the vent?

(b) Suppose that water is flowing into the tank at exactly the same volume flowrate as that of the oil flowing out of the tank. In which direction, if at all, is air moving through the vent?
