Question

A reversible thermodynamic cycle containing only three processes and producing work is to be constructed. The constraints are:
(i) there must be one isothermal process,
(ii) there must be one isentropic process,
(iii) the maximum and minimum cycle pressures and the clearance volume are fixed, and
(iv) polytropic processes are not allowed. Then the number of possible cycles are

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is D 4

(d)
Four clockwise cycles can be formed, out of which 2 cycles are formed having constant volume process and 2 cycles are formed having constant pressure process.
