The temperature of the working fluid in a real heat engine cycle changes during heat addition and heat rejection processes. The maximum and minimum temperatures of the cycle are max T and min, T respectively. If C ηis the thermal efficiency of a Carnot engine operating between these temperature limits, then the thermal efficiency, η of the real heat engine satisfies the relation
- A. C η η >
- B. C η η <
- C. C η η =
- D. 1 C η η =+
Answer: B. C η η <
