Two liquids manometer is used for measuring small pressure differences in___________________?
Correct answer: B. Gases
- A. Liquids
- B. Gases
- C. Mixture of hydrocarbons
- D. None of these
Explanation
A two-liquid manometer is commonly used to measure small pressure differences in gases because the manometric liquids can provide a sensitive level displacement. For liquids, the pressure difference is often measured with a differential manometer.
