Measurement of pressure in ammonia reactor is done by __________________?
Correct answer: A. Bourdon gauge
- A. Bourdon gauge
- B. U-tube manometer
- C. Inclined tube manometer
- D. Pirani gauge
Explanation
A Bourdon gauge is a robust mechanical instrument for measuring the relatively high pressures encountered in an ammonia reactor. U-tube and inclined manometers are generally used for lower pressure differences, while a Pirani gauge measures vacuum through thermal conductivity.
