Flue gas discharge velocity through chimney of a big thermal power plant may be around ________________ m/sec?
Correct answer: B. 10
- A. 0.5
- B. 10
- C. 50
- D. 500
Explanation
Flue-gas velocity in a large power-plant chimney is of the order of 10 m/s. Values such as 0.5 m/s would give poor discharge, while 50 or 500 m/s are unrealistically high.
