Calculate the capillary effect in millimeters in a glass
tube of 4 mm diameter, when immersed in water
and mercury respectively. The temperature of the
liquid is 20°C and the values of the surface tension of
water and mercury in contact with air are 0.073575
N/m and 0.51 N/m respectively. The angle of contact
for water is zero and that for mercury is 130⁰. Take
density of water at 20°C as equal to 998 kg/m³.
