QUESTION:
Refrigerant-134a at 1 MPa and 1008C is throttled to a pressure of 0.8 MPa. Determine the reversible work and exergy destroyed during this throttling process. Assume the surroundings to be at 308C.
ANSWER:Step 1 of 4
Refrigerant-124a is throttled from a specified state to a specified pressure. The reversible work and the exergy destroyed during this process are to be determined.
Assumptions are
1. This is a steady-flow process since there is no change with time.
2. Kinetic and potential energy changes are negligible. 3 Heat transfer is negligible.
