Answer to Question #301538 in Mechanical Engineering for hai

Question

. A gas turbine plant receives air at 1 bar and 290°K and compresses it to 5 bar. If the temperature of air after compression is 1000°K; find the thermal efficiency of the turbine.

Answer 1

thermal efficiency 

$\eta= 1-\frac{T_2}{T_1}= 1-\frac{290}{1000}=0.71=71$ %
