Using the Dual Air Standard Cycle and the following data:
Assume constant properties of air. R= 287 J/kgK; Cp = 1005 J/kgK; Cv = 718 J/kgK;y = 1.4
Cycle compression ratio = 11 (v1/v2)
Air conditions prior to compression: Pressure = 1.6 bar; Temperature = 298K
Heat added at constant volume = 290000 J/kg
Heat added at constant pressure = 579000 J/kg
