Refrigerant-134a of mass 1 kg undergoes two processes in series in a piston-cylinder assembly. at the initial state, the refrigerant is saturated vapour at a pressure of 25 bar. process 1-2: isothermal compression until all the mixture becomes saturated liquid. process 2-3: the refrigerant is cooled at constant volume to a pressure of 18 bar. a. sketch the processes on p-v and t-v diagrams, indicating clearly the path and direction of the processes determine: i. the specific volume and specific internal energy of the refrigerant at b. ii. iv. v. the end of the isothermal process. the state of the refrigerant at the work done in each process, in kj. the heat transfer in each process, in kj. (0.0010566 m3/kg, 166.99 kj/kg, 0.966 %,-14.699 kj, 0 kj,-111.159 kj,-23.52 kj)

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
