how to know the maximum and minimum temperature for cycle in.
Carnot thermal efficiency 60%
heat transfer during isothermal expansion 40kj
pressure is 5.6bar and volume is 0.3m^3
One kilogram of air as an ideal gas executes a Carnot power cycle having a thermal efficiency of 60%. The heat transfer to the air during the isothermal expansion is 40 kJ. At the end of the isothermal expansion, the pressure is 5.6 bar and the volume is 0.3 m³.
(a) Sketch the cycle on p-v coordinates.
(b) Determine the maximum and minimum temperatures for the cycle, in K.
(c) Determine the pressure and volume at the beginning of the isothermal expansion in bar and m³, respectively.
(d) Determine the work and heat transfer for each of the four processes, in kJ
The Attempt at a Solution
i know how to sketch the pv coordinates diagram however i am struggling to find the maximum and minimum T.
