The opening in a sprayer nozzle that regulates the flow is known as what?

Explanation:
The opening that regulates the flow from a sprayer nozzle is the orifice. This small passage sets how much liquid can pass at a given pressure, so it directly determines the flow rate and ultimately the amount applied. The nozzle as a whole shapes the spray pattern and droplet size, but the actual control of flow comes from the size of the orifice. If the orifice is made smaller, the flow decreases; a larger orifice increases flow. The other terms—nozzle refers to the whole component, swath is the width of the spray coverage, and spray is the discharge itself—do not describe the specific control point responsible for regulating flow.
