An inventor claims to have developed a power cycle capable of developing a net work output of 410 kj for an energy input by heat transfer of 1000 kj. the system undergoing a cycle receives the heat transfer from hot gases at a temperature of 500 k and discharges energy by heat transfer to the atmosphere at 300 k. evaluate the inventor

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
