For every 1 foot that the tank is above the discharge outlet, how much PSI of pressure is generated?

For every 1 foot of elevation, there is a specific conversion factor that allows us to calculate the pressure generated by the weight of the water above the discharge outlet. In hydraulic systems, this is known as hydrostatic pressure.

The key principle is that hydrostatic pressure is calculated using the formula:

Pressure (PSI) = Height (in feet) × 0.433 (PSI/foot).

This means that for every foot of water height above the outlet, 0.433 PSI of pressure is created due to gravitational effects.

Thus, when considering the elevation of water in a tank, for every foot of vertical rise, 0.433 PSI of pressure is generated at the outlet. This value is derived from the density of water (around 62.4 pounds per cubic foot) and the acceleration due to gravity.

Therefore, the correct answer reflects that understanding of fluid mechanics regarding how pressure changes with elevation in a water system.
