WebAug 27, 2014 · Some fully-aquatic fishes routinely leap out of the water and strand themselves on land to avoid aquatic predators or other inhospitable conditions . However, a stranded fish faces a series of challenges when attempting to return to the water. First, the fish must determine its position on land, relative to the aquatic environment. WebIn simple terms, the mathematical constant 2.31 converts a unit of energy against gravity into a unit of force against any other area. This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet.

The tube will have to be quite high for a typical domestic pump. If the discharge pressure is 40 psi the tube would have to be 92 feet high. WebEx: If your home has a static water pressure of 55 psi, and you have a section in your backyard that is 11 feet higher than your house you would subtract 5 psi which gives you a total psi of 50. The calculation is 11 feet higher x 0.433 (rounded up = 0.5). Every foot of elevation is equal to 0.422 PSI change in water pressure. calories burned during fasting
