When the tube is in its vertical position, the drop forms a column with a length of a 2cm, b. 4cm, and c. 2.98cm. The internal diameter of the capillary tube is 1 mm. Determine the radii of curvature of the upper and lower meniscuses in each case. Consider the wetting to be complete. Surface tension of water =0.0075 N/m

A barometer contains two uniform capillaries of radii 1.44×10 ^−3 m. If the height of liquid in narrow tube is 0.2 m more than that in wide tube An open capillary tube contains a drop of water. When the tube is in its vertical position b. 4cm calculate the true pressure difference. Density of liquid=10^3 kg/m^3 surface tension =72×10^−3 N/m and g=9.8m/s^−12. the drop forms a column with a length of a 2cm
