1. What is the Fire Sprinkler Flow Equation?

The Fire Sprinkler Flow Equation calculates the flow rate of water from a fire sprinkler head based on the K-factor and the water pressure. This is essential for fire protection system design and verification.

2. How Does the Calculator Work?

The calculator uses the fire sprinkler flow equation:

Where:

• \( K \) — K-factor constant specific to the sprinkler head (gpm/psi^0.5)
• \( Pressure \) — Water pressure at the sprinkler head (psi)

Explanation: The equation shows that flow is proportional to the square root of pressure, with the K-factor representing the sprinkler head's flow characteristics.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculation is crucial for designing effective fire protection systems, ensuring adequate water coverage, and meeting fire safety codes and standards.

4. Using the Calculator

Tips: Enter the K-factor specific to your sprinkler head and the water pressure in psi. Both values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical K-factor for sprinkler heads?
A: Common K-factors range from 2.8 to 25.2, with 5.6 being standard for most residential applications.

Q2: How does pressure affect flow rate?
A: Flow rate increases with the square root of pressure. Doubling the pressure increases flow by approximately 41%.

Q3: Why is this calculation important for fire safety?
A: It ensures sprinkler systems deliver adequate water to control or extinguish fires, protecting lives and property.

Q4: Are there limitations to this equation?
A: The equation assumes turbulent flow and may need adjustment for very low pressures or specific sprinkler designs.

Q5: Can this calculator be used for all sprinkler types?
A: Yes, but you must use the correct K-factor for your specific sprinkler head as provided by the manufacturer.
