Problem
1. A flow of air at 1000 kPa, 300 K is throttled to 500 kPa. What is the irreversibility? What is the drop in flow exergy?
2. A power plant has an overall thermal efficiency of 40%, receiving 100 MW of heat transfer from hot gases at an average of 1300 K, and rejects heat transfer at 50oC from the condenser to a river at ambient temperature 20oC. Find the rate of both energy and exergy (a) from the hot gases and (b) from the condenser.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
