Q. A closed gas turbine works on
Solution:
- Joule’s cycle is the cycle for the air engine proposed by Joule.
- In it air is taken by a pump from a cold chamber and compressed adiabatically until its pressure is equal to that of the air in a hot chamber, into which it is then delivered, thereby displacing an equal amount of hot air into the engine cylinder.
- Here it expands adiabatically to the temperature of the cold chamber into which it is finally exhausted.
- This cycle, reversed, is used in refrigerating machines.
- It is also called Brayton cycle.
