Hello Sir,
Good Night.
I have a question in my homework related thermodynamics lesson.
The following below is my question. Please advice, thank you

 

The ideal Otto cycle has a compression ratio of 8. At the start of the compression process, the air is at 95 kPa and 27 °C, and 750 kJ/kg of heat is transferred to the air during the constant volume heat addition process. Taking into account the variation of the specific heat with temperature, determine: Given Contant Volume = 800 kj/kg (a) the pressure and temperature at the end of the heat addition process, (b) net work output, (c) thermal efficiency, and (d) the average effective pressure for the cycle.
