## Homework Statement

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

## Homework Equations

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.
