5 kg of air in a piston cylinder assembly undergoes a Carnot power cycle. Heat is received at temperature?1=727°C and rejected at ?3=27°C.During the heat input process, the pressure changes from ?1=1200kPa to ?2=900kPa, respectively. Assume the air behaves as an ideal gas with constant specific heats. Determine: a.pressures [kPa] at beginning and end of the isothermal heat rejection process (?3,?4) b.heat transfer from high temperature source [kJ] c.thermal efficiency d.net work output for cycle [kJ]
