Answer:
88.9 %
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
[tex]\eta = 1- \frac{T_{c}}{T_{H}}[/tex]
[tex]\eta = 1- \frac{704.3}{6371}[/tex]
η = 0.889
η = 88.9 %
thus, the efficiency is 88.9 %.
