Pure water at 60F has about 27.78 inches of water column (INWC or INWG) per psi or approximately 0.43197 psi/ft. This is from memory; but it should be close. Fresh water: 0.43 psi per foot Sea water: 0.44 psi per foot. So, for each additional 10 feet of depth, figure about 4.3 to 4.4 psi increase in pressure. You can calculate this yourself by using the fact that fresh water weighs about 62.4 pounds per cubic foot (pcf) and sea water weighs about 64 pcf.
A.Find the difference in elevation 5460 feet â 5320 feet = 140 feet of head B.Convert feet of head to psi 140 feet = 60.6 psi 2.31 4. A discharge pressure gauge on a pump reads 72 psi when the pump is running.The pressure gauge at the top of a hill 40 feet above the pump reads 45 psi.hat is the volume of the tank? A. Calculate the volume 3.1416 x 30' x 30' x 12' = 33,900 cubic feet (ft 3) or 60' x 60' x 0.785 x 12' = 33,900 cubic feet (ft 3) V OLUMES IN G ALLONS It is often necessary to calculate a volume of a tank or pipe in gallons rather than cubic feet.
