What determines the pattern and quantity of a water spray head?

• A. Water Pressure
• B. Water Velocity
• C. Sprinkler Position
• D. Spray Nozzle

Answer: (D)

The nozzle determines both how much water comes out and how it is spread. The size of the nozzle’s orifice sets the flow rate (how many gallons per minute) at a given operating pressure. The design of the nozzle, together with the deflector, also shapes the spray pattern (for example, full circle, half circle, or a specific arc). While pressure influences how far the spray travels and how forcefully it exits, it doesn’t set the pattern itself—the nozzle and its deflector do. Sprinkler position affects where the water lands relative to other heads, but it doesn’t change the nozzle’s programmed pattern.
