Q1/Consider a liquid flow system consisting of a sealed tank with noncondensible gas above the liquid as shown in the following figure: li Pg Pa H 9 Cross-sectional area = A Derive an unsteady-state model relating the liquid level h to the input flow rate qi. Is operation of this system independent of the ambient pressure Pa? You may make the following assumptions: (i) The gas obeys the ideal gas law. A constant amount of M moles of gas is present in the tank. (ii) The operation is isothermal. (iii) Assume the relation of flow through the valve (q=C, AP) If the tank open to atmosphere (unsealed), derive the unsteady-state model, and show that if this system is independent of Pa or not.
