Discussion :: Surveying - Section 1 (Q.No.46)
|Deepak said: (Sep 13, 2016)|
|The correct answer should be A.|
|Batman said: (Oct 18, 2016)|
The correct answer is A, as sensitivity is l/r.
|Pider said: (Nov 17, 2016)|
|Right @Batman &@Deepak.|
|Oyke Mallick said: (Jan 9, 2017)|
|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.
Book C. L Kochher page 261.
|Gagan said: (Jan 9, 2017)|
|In GS Pandhi, answer D is right.|
|Ravi Raja said: (Feb 3, 2017)|
|In formula, R stand for the radius of curvature of bubble Tube.|
|Balveer said: (Mar 20, 2017)|
|Option D is right. I agree.|
|Radha said: (Jul 13, 2017)|
|Actually, all are correct. But viscosity is very important, in bubble tube which others depend on it. So D.|

|Chandrakantgadhavi said: (Dec 10, 2018)|
|If surface tention decrease with rise of temperature, and viscosity decrease with rise temperature then why sensitivity of bubble tube get decrease whether it's inversely proportional to viscosity and surface tention?|
|Anil said: (Mar 29, 2019)|
|Sensitivity increases with decrease in viscosity of the liquid.
Sensitivity = d|r.
|Jimmi Patel said: (Dec 29, 2019)|
|Sensitivity of liquid is depend on viscosity.|
|Mayank Mehra said: (Apr 24, 2020)|
Thanks for giving the correct explanation.
|Rockie said: (Feb 9, 2021)|
|The correct option is B.|
|Mjm Gcek said: (Aug 13, 2021)|
|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.
|Meera Krishna said: (Nov 12, 2021)|
|I think due to increase in viscosity and surface tension, the length of the bubble decreases (as the liquid tends to become more spherical shape). Since the length of bubble decreases, the sensitivity also decreases. So, option D is correct.|
