A cylinder-piston arrangement contains 2.5 kg of ammonia at 0.8 MPa and 30 °C (State 1). The system is cooled down following an isochoric process until it reaches 10 °C (State 2). The system is cooled down following an isobaric process until the liquid is saturated (State 3).
Calculate:
Volume (V1) and specific volume (v1) at State 1.
Pressure (P2) and define State 2. Find quality if saturated.
Define State 3 and find volume (V3) and specific volume (v3) at State 3.
Show the process in a P-v diagram
Calculate the work for the process.
Calculate the process heat transfer [Q] and [q].
