Question

From the given sets of statements regarding manometric fluid, identify the incorrect statement.

• A. Kerosene can be used as a manometric fluid
• B. Saline can be used as a manometric fluid
• C. Alcohol can be used as a manometric fluid
• D. Water can be used as a manometric fluid

Answer 1

Answer:

B. Saline can be used as a manometric fluid

Manometers work on the principle of balancing the column of liquid whose pressure is to be determined. Mercury is the mostly used manometric liquid due to its non- evaporating quality, sharp meniscus and reasonably stable density. Water can be used for small pressure differences and low level vacuum. Alcohol and kerosene are also sometimes used as manometric liquids. The incorrect statement is that saline can be used as a manometric fluid.
