Comparison between efficiencies of Brayton cycle & Otto cycle - Thermodynamics

Q.  For the same compression ratio, how is the efficiency of the Brayton cycle compared with the efficiency of Otto cycle?
- Published on 20 Aug 15

a. Efficiency of the Brayton cycle is higher than the efficiency of the Otto cycle, for the same compression ratio
b. Efficiency of the Brayton cycle is lower than the efficiency of the Otto cycle, for the same compression ratio
c. Efficiency of the Brayton cycle is same as that of the Otto cycle, for the same compression ratio
d. cannot say

ANSWER: Efficiency of the Brayton cycle is same as that of the Otto cycle, for the same compression ratio
