A piston cylinder holds 2 kg of refrigerant 134a at 320 kPa and a quality of .9 while the piston is resting on a stop (state 1). Heat is added until the pressure reaches .5 MPa (state 2) when the piston begins to move. Heat addition Continues unitl an additional 25 kJ/kg is transferred (state 3).
1.Determine the heat transfer durng the first process 1 to 2 in kJ.
2.Determine the work from 2 to 3 in kJ.
