Desirable properties of good manometric liquid should have;

-> Low-freezing point.
-> High boiling point.
-> Non wetting characteristics.
-> Low surface tension.
-> Chemically inert.
-> Clear visible interface.
-> Ability to maintain density at various temperatures.

Should have high density to decrease the column height and due to which we can measure more range of pressure.

Yogendra said:   8 years ago
Why high surface tension required?

@Vinit.

Non-wetting and low surface tension are contradictory.

Rajasekhar said:   8 years ago
Higher surface tension enables less wetting of the tube and so these type of liquids are desirable in manimeters.

C.r.meena said:   8 years ago
High density is the correct answer.

Durugappa said:   8 years ago
It should low surface tension.

Then why we use mercury as a manometric fluid?

I think the given answer is correct.

Rinku Meena said:   8 years ago
High density is correct.

Vijay rajput said:   7 years ago
High density is the correct.
