1. Apply the exergy equation to solve Problem 8.36.
Problem 8.36
A refrigerator removes 1.5 kW from the cold space at -10?C, using 750 W of power input while it rejects heat to the kitchen at 25?C. Find the rate of irreversibility.
2. Evaluate the steady-state exergy fluxes due to a heat transfer of 50 W through a wall with 600 K on one side and 400 K on the other side. What is the exergy destruction in the wall?
