MCQ
In joule cycle heat input is provided to ............
Options
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)
Solution
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
