Which term describes stored potential energy in the water column that can push water through hose when water is not moving?

• A. Dynamic Pressure
• B. Residual Pressure
• C. Static Pressure
• D. Gauge Pressure

Answer: (C)

Stored potential energy in the water column that can push water through a hose when water isn’t moving is static pressure. It’s the pressure present in the system when there is no flow, representing the energy already stored in the water due to elevation and any pump pressure. When you open a nozzle or valve, that static pressure becomes the driving force pushing water through the hose. Dynamic pressure, on the other hand, comes from the motion of water itself—the energy of moving water. Gauge pressure is simply pressure measured relative to atmospheric air, often describing static pressure, while residual pressure is what remains after some flow has been stopped and isn’t the general store of energy in the system.
