Question

The capillary rise at 20 degree c in glass having 1mm diameter containing water is

Answer 1

Answer:

The capillary rise = 29.56 mm

Explanation:

h = 4 a cos Ф / p g d

Here Ф = 0° for water and glass, surface tension = 0.0725 N/m

h = 4 x 0.0725 x cos 0 / (1000 x 9.81 x 10⁻³)

h = 0.02956 m

h = 29.56 mm  = the capillary rise
