PVy = constant, holds good for an isentropic process, which is_________________?
Correct answer: A. Reversible and adiabatic
- A. Reversible and adiabatic
- B. Isothermal and irreversible
- C. Reversible and isothermal
- D. Adiabatic and irreversible
Explanation
An isentropic process has constant entropy and, in the standard engineering model, is both adiabatic and reversible. Reversibility is needed because an irreversible adiabatic process generates entropy.
