2.2 lb of ammonia in a piston cylinder assembly undergoes two isothermal processes in series. the first process from an initial state where p1=120lbf/in^2 with a quality is 85% to a final state where the ammonia is saturated vapor. during the second process energy is added to the system by heat transfer at a rate of 44.77 Btu/lb and continues until the pressure has fallen to p2=50lbf/in^2. kinetic and potential energy effects are negligible. determine the heat transfer and work for both processes on a p-v diagram.
