An air receiver contains air at 16 bar and 42°C. A valve is opened and some air is allowed to blow out to atmosphere. The pressure of the air in the receiver drops rapidly to 12 bar when the valve is then closed. Assuming that the mass in the receiver undergoes a reversible adiabatic process, calculate the initial and final mass of air if you know that the amount of air which has left the receiver is 18.04 kgs.
