QUESTION Question 2 (15 Marks) 1- In an Otto cycle air at 17 C and 1 bar is compressed isentropically (adiabatically) until the pressure is 15 bar. The compression ratio is 6.91 and heat is added at constant volume until the pressure rises to 40 bar. Determine the following: a- Heat supplied to the system and heat rejected from the system. b- The network output per cycle [kJ/kg]. c- The thermal efficiency. d- Mean effective pressure for the cycle. Take: for air, C = 0.717 KJ/kg. K, R = 0.287 KJ/kg. K, k= 1.4 TA Isentropic 9 gout lou V=const. Isentropic
