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)

A 76-year-old client is admitted to a medical-surgical unit 2 days after a total hip replacement. During assessment, the nurse notes that the client reports sudden shortness of breath and chest pain that worsens with inspiration. Assessment Findings: BP 92/58 mm Hg HR 118/min RR 30/min SpO₂ 88% on room air Temperature 37.1°C (98.8°F) Right calf is warm and swollen Based on the client’s assessment findings, which potential condition should the nurse identify as the highest-priority hypothesis?
