Moderate
Rankine cycle efficiency of a good steam power plant may be in the range of____________?
Correct answer: B. 35 to 45 per cent
- A. 15 to 20 per cent
- B. 35 to 45 per cent
- C. 70 to 80 per cent
- D. 90 to 95 per ceut
Explanation
A practical steam power plant loses efficiency through boiler, turbine, generator, condenser and pumping losses, so its overall Rankine efficiency is commonly around 35 to 45 percent. Values such as 70 to 95 percent are not realistic for a complete steam plant.
