10. An air-standard cycle operating as a closed system is used to convert a portion of heat into work by using the following processes: Process 1-2: Constant pressure heat addition Process 2-3: Isentropic expansion Process 3-4: Constant volume heat rejection Process 4-1: Isothermal compression where Wb=210kJ and V4=8.20m3 During the isothermal compression process (Process 4-1), heat is rejected from air to maintain a constant temperature. In State 1 , the system has a volume of 1m3, at a pressure of 100kPa, and a temperature of 300K. After heat addition, a temperature of 1200K is reached (State 2). Using the information provided below, determine: a) Total heat added (kJ). [5 marks ] b) Net work produced (kJ). [8 marks ] c) The total thermal efficiency of the cycle. [2 marks ] d) TS diagram of the cycle. [5 marks] [ total =20 marks ] Data for air: R=0.2870kJ/kgKCp=1.005kJ/kgKCv=0.718kJ/kgKk=1.4
