Q2. An engine is operating on the Atkinson cycle. The volumetric compression ratio is r = 9.2 and the pressure ratio is rp = 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. T = 300K P = 100kPa V = W12 = 912 = S-S = m/kg kJ/kg kJ/kg T = V = W23 = 923 = kJ/kgK S3-S = e) Find nth Wnet/9in. f) Find: P = 7th = 1. K kPa m/kg kJ/kg kJ/kg c) Find Tex d) Find Wnet W12 + W23 + W34 + W41. = kJ/kgK k (Tex - Tv) rk-1 (rk r. 1-k - rv)' ex and T3 = P3= V3 = W34 = 934 = S4-S3 = K kPa m/kg kJ/kg kJ/kg 7th = 1 - T = V4 = W41 = 941 = kJ/kgK S-S4= k P = K kPa m/kg kJ/kg kJ/kg (1)-1) (p-1) kJ/kgK
