(a) How high will water rise in a glass capillary tube

Solution 79PE

Step 1 of 5

Here we need to calculate how high the water will rise in a glass capillary tube which has radius of  with contact angle . Also, we need to calculate gain in gravitational potential energy of water and need to discuss about the sources of this energy.

Given data,

Radius of tube,

Using                 

Acceleration due to gravity,

Density of water,

Surface tension of water,

contact angle,

To find,

1. Height,
2. Gain in gravitational potential energy,
