An air-standard dual cycle has a compression ratio of 18 and a cutoff ratio of 1.1. The pressure ratio during constant-volume heat addition process is 1.1 At the beginning of the compression, P1=90 kPa, T1=18oC, and V1=0.003 m3. How much power will this cycle produce when it is executed 4000 times per minute? Use constant specific heats at room temperature.
