Question

What is the maximum possible thermal efficiency of a gas power cycle when using thermal energy reservoirs at 11008F and 808F?

Answer 1

88.9 %

Step-by-step explanation:

temperature of hot reservoir, TH = 11008 F = 6371 K

temperature of cold reservoir, Tc = 808 F = 704.3 K

The efficiency of plant is given by

`\eta = 1- (T_(c))/(T_(H))`

`\eta = 1- (704.3)/(6371)`

η = 0.889

η = 88.9 %

thus, the efficiency is 88.9 %.
