Ai inventor proposes a four -stroke cycle running on helium. Theengine has a compression ratio of 8 and maximum operatingtemperature of 1,500 K. The atmospheric conditions are temperatureof 300 K and pressure of 100 kPa. The processes can be approximatedas below:
1- 2 isentropic compression
2- 3 constant volume heat addition
3- 4 isentropic expansion
4- 1 constant pressure heat removal
a.
Plot P-v and T-s diagrams for this cycle.
b.
Determine state conditions at the end of each step by filling upthe table below.
c. Heat addition
d. Net work
e. Thermal efficiency
Hint: Cp= 5.193 kJ/kg.K, Cv = 3.116 kJ/kg.K, R = 2.077 kJ/kg.K,k = 1.667
Please show work for all questions a-e. Thank You
