______ is the pressure of water when it is not moving.

Explanation:
Static pressure is the pressure in the water when there is no movement. When water isn’t flowing, there’s no velocity energy, so the pressure you measure reflects only the potential energy of the water in the system. If water starts moving, velocity contributes kinetic energy, giving dynamic (velocity) pressure, and the pressure during flow is described differently (often as residual or flow pressure, depending on the context). So the pressure of water when it is not moving is static pressure.
