How much pressure does one foot of water generate?

One foot of water generates approximately 0.433 PSI (pounds per square inch) due to the density of water and the relationship between pressure, density, and height. This value is derived from the hydrostatic pressure formula, which states that pressure increases with depth in a fluid.

In the case of water, the pressure at a given depth is calculated using the formula:

Pressure (PSI) = Depth (feet) × Density of water (62.4 lb/ft³) ÷ 144 in²/ft².

Since there are 12 inches in a foot, when conducting this calculation for one foot of water, the results show that one foot of water indeed exerts about 0.433 PSI at the surface. This knowledge is crucial for understanding irrigation systems and ensuring proper water pressure for effective irrigation practices.

Other values listed do not accurately reflect the established physics of fluid pressure relevant to water systems and thus are not considered correct in this context.
