Discussion Forum : Surveying - Section 1 (Q.No. 46)
The sensitiveness of a level tube decreases if
radius of curvature of its inner surface is increased
diameter of the tube is increased
length of the vapour bubble is increased
both viscosity and surface tension are increased.
Answer: Option
No answer description is available. Let's discuss.

Sensitivity is L/R which means it is directly proportional to the length and inversely proportional to the radius of curvature soo A is the correct answer.

Option D is completely wrong as they are directly proportional to sensitivity.

The correct answer should be A.

Right @Deepak.

The correct answer is A, as sensitivity is l/r.

PIDER said:   7 years ago
Right @Batman &@Deepak.

In GS Pandhi, answer D is right.

Oyke mallick said:   7 years ago
Right option is D because we know sensitiveness is also increased by the increase in the length of the bubble and by a decrease of viscosity and surface tension of the liquid in the level tube ref.

In formula, R stand for the radius of curvature of bubble Tube.

Balveer said:   7 years ago
Option D is right. I agree.

Radha said:   6 years ago
Actually, all are correct. But viscosity is very important, in bubble tube which others depend on it. So D.

Yes @Radha.
