Working principle of manometer comprises of balancing a coloumn of liquid against the pressure to be measured. Inclined tube manometer is especially used for the measurement of ______________ pressure?
Correct answer: A. Small differential
- A. Small differential
- B. Atmospheric
- C. Absolute
- D. Gage
Explanation
The elongated liquid column in an inclined manometer produces a larger readable displacement for a small pressure difference. It is therefore especially useful for measuring small differential pressures rather than atmospheric or absolute pressure.
