QUESTION:
Consider a Carnot cycle executed in a closed system with 0.6 kg of air. The temperature limits of the cycle are 300 and 1100 K, and the minimum and maximum pressures that occur during the cycle are 20 and . Assuming constant specific heats, determine the net work output per cycle.
ANSWER:
Step 1 of 3
A Carnot cycle with the specified temperature limits is considered.Refer to figure below.
The net work output per cycle is to be determined.
We assume that air is an ideal gas with constant specific heats.
The properties of air at room temperature are , , , and (Table A-2).
