Small pressure differences in liquids is measured using a/an__________________?
Correct answer: D. Inclined tube manometer
- A. U-tube manometer
- B. None of these
- C. Pitot tube
- D. Inclined tube manometer
Explanation
An inclined-tube manometer magnifies the vertical movement of the manometric liquid along a longer inclined length, making it sensitive to small pressure differences. A standard U-tube is less sensitive, while a Pitot tube measures velocity-related pressure.
