(1) Problem 9-33 (show the solution process indetail)
9-33 An ideal Otto cycle has a compression ratio of 8. At thebeginning of the compression process, air is at 95 kPa and 27Â°C,and 750 kJ/kg of heat is transferred to air during theconstant-volume heat-addition process. Taking into account thevariation of specific heats with temperature, determine(a) the pressure and temperature at the end of theheat-addition process, (b) the net work output,(c) the thermal efficiency, and (d) the meaneffective pressure for the cycle. Answers: (a)3898 kPa, 1539 K, (b) 392.4 kJ/kg, (c) 52.3percent, (d) 495 kPa
(2) Problem 9-33 but assume constant specificheats.
Please help with problem 2 only. Thank you
