Calculate the capillary effect in mm in a glass tube of 4mm diameter, when immersed in (1)water, (2)mercury. The temperature of the liquid is 25°C and the values of surface tensions of water and mercury at 25°C in contact with air is 0.0735 and 0.59N/m respectively. The angle of contact for water is 0° and 130° for mercury . Take the density of water 1000 kg/m³ , specific gravity of mercury is 13.6.
