1. Apply the exergy equation to solve Problem 8.18.
Problem 8.18
A refrigerator should remove 1.5 kW from the cold space at -10?C while it rejects heat to the kitchen at 25?C. Find the reversible work.
2. Apply the exergy equation to solve Problem 8.35 with T0 = 20?C.
Problem 8.35
A 20?C room is heated with a 2000-W electric baseboard heater. What is the rate of irreversibility?
