A tube is placed vertically in a beaker of salt water with a specific gravity of 1.15. The interfacial tension between the air and the water is 32 mN/m and the contact angle is 30 degrees, calculate:

a) Capillary pressure in psi if the tube diameter is 0.0001 cm.

b) Capillary rise of water in tube.

c) If the cap rock thickness is 2ft, do you think this will stop water migration?

d) Radius in inches of the largest pore, if the displacement pressure is 25 kPa.
