A tube is placed vertically in a beaker of oil (sp. gr. = 0.85). The interfacial tension between air and oil is 42 dynes/cm and the contact angle is 50 degree. Calculate: 1. Is this system water wet? Why? 2. Capillary rise of oil in the tube if the tube diameter is 0.01 centimeters 3. Capillary pressure in psi 4. J-function is permeability is 25 md and porosity is 0.17 5. If the displacement pressure is 20.0 atm. What is the average pore size? A tube is placed vertically in a beaker of oil (sp. gr. = 0.85).
