A piston-cylinder assembly contains ammonia, initially at a temperature of -20°C and a quality of 50%. The ammonia is slowly heated to a final state where the pressure is 6 bar and the temperature is 120°C. While the ammonia is heated, its pressure varies linearly with specific volume. For the ammonia, determine the work and heat transfer, each in kJ/kg.
Understand the Problem
The problem describes a thermodynamic process involving ammonia in a piston-cylinder assembly. We need to determine the work and heat transfer (both in kJ/kg) during the heating process, given the initial and final states of the ammonia and the fact that pressure varies linearly with specific volume.
