Question: An ideal Otto cycle with argon as the working fluid has a compression ratio of 8.5. The minimum and maximum temperatures in the cycle are

An ideal Otto cycle with argon as the working fluid has a compression ratio of 8.5. The minimum and maximum temperatures in the cycle are 350 K and 1630 K. Accounting for variation of specific heats with temperature (that is, using the IG model for air), determine (a) The amount of heat transferred to the air during the heat addition process,
(b) The thermal efficiency and
(c) The thermal efficiency of a Carnot cycle operating between the same temperature limits.
