A closed cycle gas turbine unit operating with max. And min. Temp. Of 760 and 20 Celsius deg has a pressure ratio of 7/1. Calculate the thermal efficiency and work ratio?
Ans = 42.7 % , 0.505
My answers are :
Efficiency 42.7 % which is correct.. but work ratio = 1.977.
T1 and T3 are given.T2 is 510.87 and T4 is 592.38.. these values i get it by solving..
Acc. To graph T4 should be less than T2....
Can you solve it for me.. plz
