Steam expands in a turbine steadily at a rate of 40,000
Chapter 7, Problem 154P(choose chapter or problem)
Steam expands in a turbine steadily at a rate of \(40,000 \mathrm{~kg} / \mathrm{h}\), entering at \(8.MPa and 500^{\circ} \mathrm{C}\) and leaving at 40 kPa as saturated vapor. If the power generated by the turbine is , determine the rate of entropy generation for this process. Assume the surrounding medium is at \(25^{\circ} \mathrm{C}\).
