Areverse carnot cycle is used for cooling. r134a is the substance. the cool side is held at 0oc and the warm side at 20oc. the r134a condenses completely from a saturated vapor to a saturated liquid during the heat rejection process. what is the cop of this cooling cycle?
show using

a) a thermodynamics analysis
b) the carnot corollary

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
