Repeat Prob. 9-50 when the state of the air at the beginning of the compression is 80
Question:
Prob. 9-50
An air-standard dual cycle has a compression ratio of 14 and a cutoff ratio of 1.2. The pressure ratio during the constant-volume heat addition process is 1.5. Determine the thermal efficiency, amount of heat added, the maximum gas pressure and temperature when this cycle is operated at 80 kPa and 20oC at the beginning of the compression. Use constant specific heats at room temperature.
