Figure shows a capillary rise H. If air is blown through the horizontal tube as shown, then rise in capillary tube will be:
Figure shows a capillary rise H. If air is blown through the horizontal tube as shown, then rise in capillary tube will be:
Show Hint
Higher fluid speed implies lower pressure (Bernoulli’s principle).

- \( =H \)
- \( >H \)
- \(
- zero
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Blowing air increases velocity of air above liquid.
Step 2: By Bernoulli’s principle, pressure above liquid decreases.
Step 3: Lower pressure causes greater capillary rise.
