Question

In a closed system contains R-134a and it undergoes an isothermal process from state 1 to
state 2. The initial temperature and pressure of R-134a are 320 kPa and 40°C
respectively. The final quality of R-134a is 50 percent. Find the specific work and heat
transfer during the isothermal process​

Answer 1

Answer:

Answers: 40.6 kJ/kg, 130 kJ/kg.

Explanation :Refrigerant-134a at 320 kPa and 40∘C undergoes an isothermal process in a closed system until its quality is 45 percent. On a per-unit-mass basis, determine how much work and heat transfer are required.
