For maximum discharge through a chimney, its height should be___________________?
Correct answer: D. Equal to the height of the hot gas column producing draught
- A. 200 meters
- B. Infinitely long
- C. More than 105.7 metres
- D. Equal to the height of the hot gas column producing draught
Explanation
Increasing chimney height increases draught only up to the optimum condition; maximum discharge occurs when the chimney height equals the effective height of the hot gas column producing the draught. An indefinitely long chimney would add resistance and would not maximise flow.
