Question

The capillary rise of water in the glass tube is given by

• A. $h=\frac{2\sigma cos\theta}{\omega d}$
• B. $h=\frac{3\sigma cos\theta}{\omega d}$
• C. $h=\frac{4\sigma cos\theta}{\omega d}$
• D. $h=\frac{6\sigma cos\theta}{\omega d}$

Answer 1

Answer:

C. $h=\frac{4\sigma cos\theta}{\omega d}$

The capillary rise of water in a glass tube depends on the surface tension, angle of contact, tube diameter, and specific weight. The formula for the capillary rise is,$h=\frac{4\sigma cos\theta}{\omega d}$
