an incompressible, nonvolatile liquid is pumped into the bottom of a closed tank of volume vo and diameter d. at the start of filling, the tank contains only an inert, ideal gas, such as air, that is insoluble in the liquid. the initial pressure in the tank is po, and the supply liquid volumetric flow rate is proportional to the difference in the inlet line pressure, pin and the pressure in the tank, p (which is constant throughout the tank). the process is isothermal. a. draw a sketch of the filling process and describe in words what happens.
