An air-standard dual cycle has a compression ratio of 20 and a cutoff ratio of 1.2 The pressure ratio during the constant-volume heat addition process is 12 Determine the thermal efficiency. amount of heat added, and the maximum gas pressure and temperature when this cycle is operated at 14 psia and 70∘F at the beginning of the compression. Use constant specific heats at room temperature. The properties of air at room temperature are R=0.3704psia−ft3/lbm⋅R,cp=0.240Btu/lbm⋅R,cV=0.171 Btu/lbrn-R. and k =1.4. The maximum gas pressure is psia. The maximum gas temperature is R. The amount of heat added is Btu/libm. The thermal eficiency is % क.
