If the interfacial tension between air-mercury interface in a capillary tube is 480 dynes/cm and the contact angle through the mercury is 140, what would be the capillary pressure between oil and water if the capillary pressure between air-mercury is -15 psia? Assume that the interfacial tension between oil-water is 22 dynes/cm and the contact angle through water is 93
