Which of the following is a commonly used manometric liquid for low pressure range ?
Correct answer: A. Carbon tetrachloride
- A. Carbon tetrachloride
- B. Ethyl alcohol
- C. Glycerol
- D. Ethylene glycol
Explanation
Carbon tetrachloride is a dense, nonvolatile liquid commonly used in manometers for relatively low pressure differences, producing a larger readable column displacement than mercury. Mercury is preferred when the pressure range is high.
