Moderate
The thermal efficiency of the engine with condenser as compared to without condenser, for a given pressure and temperature of steam, is_____________?
Correct answer: A. higher
- A. higher
- B. lower
- C. same as long as initial pressure and temperature is unchanged
- D. none of the above
Explanation
A condenser reduces the exhaust pressure and permits greater expansion of the steam, increasing the turbine work and thermal efficiency. Without a condenser, steam exhausts at a higher pressure and more energy remains unused.
