Air enters the compressor of a regenerative gas-turbine engine at 300 K and 100 kPa, where it is compressed to 600 MPa and 700 K. The regenerator has an effectiveness of 80 percent, and the air enters the turbine at 1500 K. The compressor and turbine work at an isentropic efficiency of 90 percent. Assume variable specific heats for air. Draw the cycle on diagram and identify different states and processes. (5 pts) Determine all relevant properties and show them in a table format. (25 pts) Determine the amount of heat transfer in the regenerator. (5 pts) Determine the thermal efficiency of the cycle. (5 pts)

When analyzing Diesel cycle efficiency, why does the method change if the constant-specific-heat assumption is NOT used?
