What is the typical orifice size of standard sprinkler heads?

The typical orifice size of standard sprinkler heads is 0.5 inches. This size is widely used because it provides an effective balance between water flow and pressure, which is essential for extinguishing fires and ensuring adequate coverage. The 0.5-inch orifice allows for sufficient water discharge to manage fire risks in various types of structures while still being manageable in terms of system design and pressure requirements. Different applications may utilize various sizes, but 0.5 inches is the standard choice for most conventional sprinkler systems, making it a key component of fire protection engineering.
