Q2. An engine is operating on the Atkinson cycle. The volumetric compression ratio is r = 9.2 and the pressure ratio is r = 2.1. Take k = 1.4, cp = 1.005kJ/kgK. a) Draw the air-standard Atkinson cycle on a T-s diagram. b) Using air-standard cycle analysis, complete the following table. State 1 T=300 K P= 100 KPA V=0.8612 m/kg W12-430.99 kJ/kg Q12=0 KJ/KG S-S =O KJ/KG*K State 2 T=728.84 K P2=2235.13 KPA V2=0.0936 m/kg State 3 T=1530.53 P3=4693.8 KPA V3=0.0936 m/kg State 4 T4=509.66 K P4= 100 KPA V4=1.291 m/kg W41=-43.05 Q41= W23-0 Q23=574 KJ/KG S3-S= Q23=0.532 KJ/KG*K W34=1002 Q34-0 KJ/KG S4-S = 0 KJ/KGK S-S4=0.532 210.7 Q2.
