Question

The sensitiveness of a bubble tube in a level would decrease if

Answer 1

Sensitiveness or the sensitivity of a level tube is its capability of exhibiting small deviations of the tube from the horizontal. This quality depends mainly upon the radius of curvature of the level tube which may vary from 10 to 300 metres —the larger the radius, the greater the sensitiveness. Sensitiveness is also increased by increase in the length of bubble and by decrease of viscosity and surface tension of the liquid in the level tube.
