Use the formula Pressure (P) = 0.433 × height of water in feet (h) to calculate the psi for elevated water storage tanks.

The equation is as follows: It states that the pressure difference between two elevations in fluid is the product of elevation change, gravity, and density. drop with altitiue and a sea-level pressure of 1 atm.
