Throttling process is a/an _____________ process?
Correct answer: B. Irreversible and constant enthalpy
- A. Reversible and isothermal
- B. Irreversible and constant enthalpy
- C. Reversible and constant entropy
- D. Reversible and constant enthalpy
Explanation
In throttling, there is no appreciable work or heat transfer, so the steady-flow energy balance gives h1 = h2. The process is irreversible because it involves a pressure drop through a valve with entropy generation.
