Repeat Prob. 9-38E using argon as the working fluid.
Prob. 9-38E:
An ideal Otto cycle with air as the working fluid has a compression ratio of 8. The minimum and maximum temperatures in the cycle are 540 and 2400 R. Accounting for the variation of specific heats with temperature, 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.
