How many feet of water at 62 degrees F equals one pound of pressure per square inch?

One pound of pressure per square inch (psi) can be correlated to a specific height of a fluid column. In the case of water at 62 degrees Fahrenheit, the height required to generate a pressure of one psi is approximately 2.31 feet.

This relationship comes from hydrostatic principles, which dictate that pressure in a fluid is determined by the height of the fluid column above the point in question. At sea level, the density of water at this temperature is effectively constant, allowing for this standardized conversion factor.

Understanding this conversion is essential for plumbing applications, as it assists in calculations regarding water pressure in systems, helping to design plumbing networks and ensure they can accommodate the necessary pressure according to the heights at which water is delivered or stored.
