Answer to Question #101261 in Electrical Engineering for Muhammad Umar Aslam

Question

A closed cycle gas turbine unit operating is maximum and minimum temperature of 760 and 20 degree Celsius has a pressure ratio of 7/1. Calculate the ideal cycle efficiency and the work ratio

Answer 1

we can write

Where , r=1.4

Using (1) we get

In our case, we have T₁=293 K

In our case, we have T₃=1033 K

the ideal cycle efficiency is equal to

work ratio is equal to

net work is equal to

gross work is equal to

work ratio=0.5

Answer

ideal cycle efficiency 43%

work ratio=0.5
