Question

a material has a grain diameter of 0.0005 cm. What height of capillary rise will you expect? The following data applies:

The surface tension of water: 73 g/s2

Wetting angle: 0 degrees.

 

2ocos a (2) where height of rise of fluid in the capillary tube (m) o = surface tension of fluid against air ( for water, o= 0.073 kg/s? at 20°C and 0.067 kg/s at 55°C ) a = contact angle of water with the tube ( radians), ( for water, cos a 1) p= density ( for water, p= 998 kg/ m at 20°C and 986 kg/m at 55°C) g= acceleration due to gravity (g = 9.81 m/ s) r= equivalent radius of tube (m)
