A) For a devices operating on an ideal Otto cycle with a compression ratio of 9 , what is the maximum possible efficiency of the cycle? (use the cold air standard approximation) B) For a devices operating on an ideal Diesel cycle with a compression ratio of 15 and a cut-off ratio of 2 , what is the maximum possible efficiency of the cycle? (use the cold air standard approximation) C) For a devices operating on an ideal Brayton cycle with a pressure ratio of 12 , what is the maximum possible efficiency of the cycle?
