The fundamental equation of a particular fluid is UN vì = A(S – R)' where A = 2 × 10-2 (K³m³/J³). Two moles of this fluid are used as the auxiliary system in a Carnot cycle, operating between two thermal reservoirs at temperature 100°C and 0°C. In the first isothermal expansion 10° J is extracted from the high-temperature reservoir. Find the heat transfer and the work transfer for each of the four processes in the Carnot cycle. Calculate the efficiency of the cycle directly from the work and heat transfers just computed. Does this efficiency agree with the theoretical Carnot efficiency? Hint: Carnot cycle problems generally are best discussed in terms of a T-S diagram for the auxiliary system.
