the 2016 olympics are going to be held in rio de janeiro, brazil. a team of engineers is under extreme time constraints to build an enormous arena to host the events. as the team breaks ground, a small sinkhole-like area collapse occurs beneath them.

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 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
