What determines how much water a sprinkler releases and the velocity at which it is released?

The opening through which water flows—the orifice—controls how much water can pass and how fast it can leave. A larger orifice lets more water move per second under the same system pressure, increasing the discharge rate, and it also permits a higher jet velocity since more water is driven through per unit time. In sprinkler hydraulics, the discharge rate is essentially proportional to the orifice area (with pressure and discharge efficiency shaping the exact value), so the orifice size is the key determinant of both how much water is released and how quickly it exits. Orientation, location, and temperature rating mainly affect spray pattern, placement, or material limits, not the basic amount and exit speed of water.
