A capillary tube with radius 20 um and 100 mm in length is

filled with water. At time = 0, one end of the capillary tube

is inserted vertically in a beaker containing oil (Vo = 0.798)

and kept 20mm below the surface of the oil. Then, the other end is exposed to atmospheric pressure. What is the equilibrium distribution of oil and water in the capillary tube if the surface of the tube is

a. Strongly oil wet (0 = 180)

b. Intermediate wetted (0 = 90)

c. Moderately water wetted (4 = 45)

IFT between the oil and water is 25 mN/m and the IFT between air and water is 72 mN/m.
