A well$-$insulated $0\mathrm{.}012-m^3$ tank contains $13\mathrm{.}6$ kg of $R-22$ refrigerant satur. ated mixture at $30C.$ A valve is opened to recharge an air$-$conditioning system.

A$.$ Find the initial pressure, the quality of the refrigerant, and the initial volume of liquid in the tank.

B$.$ Two kilograms of refrigerant are slowly $($reversibly$)$ bled out of the tank. $($Note in the photo that the recharge tank is on a scale to measure the weight of the refrigerant.$)$ Determine the tank temperature and pressure after the refrigerant bleed if the process is adiabatic. Also find the quality of the mixture in the tank.

C$.$ After the bleed process, the temperature of the tank returns to $30C.$ Determine the final pressure. Also find the quality of the mixture and the final volume of liquid in the tank.
