• A. Reversibly at constant volume
• B. Reversibly at constant temperature
• C. Reversibly at constant pressure and temperature
• D. Reversibly at constant pressure

Answer 1

The correct option is D Reversibly at constant pressure


Process 4-1: Indicates isobaric heating of feed water, its change of phase from liquid to vapour and then its superheating in the boiler due to the heat transfer from the hot combustion flue gases to the feed water.
The state of the steam leaving the boiler is high pressure, high temperature super heated steam.
