It all depends upon the shape of the container that it is in. For example, if the water weighs 8 lbs per gallon, then the water at the bottom of a container that is a vertical pipe with cross sectional area of 1 square inch will exert a pressure of 8 psi. However, if the water is in a vertical pipe with cross sectional area of 8 square inches, then the pressure at the bottom of the pipe will be only 1 psi.
Gallon is volume, PSI is pressure. They're different things and don't translate.
#2 fuel oil = 140,000 btu/gallon. Psi does not matter.
what should your psi be around in a inground swimming pool andt it hold 12,000 gallons of water
That depends on the surface area over which the weight of the gallon of water is distributed. Divide 8.34 pounds -- the weight of a gallon of water -- by the area, in square inches, the gallon is sitting upon. If the gallon of water is in a typical plastic jug that you buy at the grocery store, it's not creating much pressure at all -- only about 2.2 ounces per square inch.
There are about 34.6 psi in 15 feet of water.
It needs at least 38 psi of incoming water.
