A tank contains a two-phase liquid–vapor mixture of Refrigerant 22 at 9 bar. The mass of saturated liquid in the tank is 25 kg and the quality is 30%. Determine the volume of the tank, in m3, and the percentage of the total volume occupied by saturated vapor.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
