The forward pressure of a water stream leaving a nozzle is referred to as what?

Explanation:
The main idea is that the force pushing the water forward as it exits the nozzle is called flow pressure. This is the discharge pressure at the nozzle—the pressure energy that drives the stream and partly converts into the jet’s velocity as it leaves. It characterizes the driving force of the flow, separate from pressures caused by gravity (head pressure), pressures left in the system after flow (residual pressure), or generic operating terminology (normal operating pressure). In practical terms, higher flow pressure at the nozzle means a stronger, farther-reaching jet.
