(Mcq) In joule cycle heat input is provided to ............


In joule cycle heat input is provided to ............


A) at constant temperatures process 

B) at constant pressure process 

C) at constant volume process 

D) at constant enthalpy process 

Correct answer : option B ( solution discussed below)


Joulr cycle is working cycle of gas power plant. Joule cycle is also called as Brayton cycle. In Brayton cycle two constant pressure process and two constant entropy process.

Process 1 - 2
Heat addition (supplied) at constant pressure 

Process 2 -3
Isentropic (constant entropy) expansion process 

Process 3-4
Heat rejection at constant pressure

Process 4 -1
Isentropic (constant entropy) compression process
