You are right, Thanks @Vinit.

Yogendra said: 8 years ago

Why high surface tension required?

Pascal said: 8 years ago

@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.

Nitin dhasmana said: 8 years ago

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: 8 years ago

High density is the correct.

Rishu said: 7 years ago

Manometer liquid should have high density and low vapour pressure.
