The difference in height between the water source and the point of use creates which pressure term?

• A. Consumption Demand
• B. Residual Pressure
• C. Elevation Pressure
• D. Back Pressure

Answer: (C)

Elevation pressure comes from the weight of a vertical column of water between the source and the point of use. Gravity creates pressure at the outlet that increases with height difference, described by P = ρ g h. Practically, each extra foot of elevation adds about 0.433 psi to the pressure at the use point. This is distinct from consumption demand, residual pressure, or back pressure, which refer to other aspects of a system rather than the pressure produced by height difference.
