An air standard dual cycle has a compression ratio of 18 and a cutoff ratio of 1.1. The pressure ratio during the constant volume heat addition process is 1.1. At the beginning of compression the pressure is 90 kPa, the temperature is 18degreeC and the volume is 0.003 m3. How much power will the cycle produce when it is executed 4000 times per minute? Use constant specific heats at room temperature.
