Extracted text: 6 A reversible power cycle R and an irreversible power cycle I nerate between the same two reservoirs. Each receives QH from the hot reservoir. The reversible cycle develops work WR while the irreversible cycle develops work W. (a) Evaluate the rate of entropy generation o for cycle I in terms of W, WR and the temperature Tc of the cold reservoir. (b) Demonstrate that o must be positive.
