Fire Demand Formula:
| From: | To: |
Fire Demand is the amount of water required to extinguish a fire. It's a critical parameter in fire protection system design and water supply planning for municipalities and industrial facilities.
The calculator uses the Fire Demand formula:
Where:
Explanation: The formula calculates the total water demand by adding the reserve storage consumption rate to the pump capacity.
Details: Accurate fire demand calculation is essential for designing adequate water supply systems, ensuring sufficient fire protection, and meeting regulatory requirements for fire safety.
Tips: Enter reserve storage in cubic meters, duration of fire in seconds, and pump capacity in cubic meters per second. All values must be positive numbers.
Q1: What is reserve storage in fire protection?
A: Reserve storage refers to the dedicated water capacity maintained specifically for firefighting purposes, separate from regular water supply.
Q2: How is duration of fire determined?
A: Duration of fire is typically based on fire safety codes and standards, which specify minimum required firefighting durations for different types of buildings and hazards.
Q3: What factors affect pump capacity?
A: Pump capacity depends on pump type, size, power source, and system design, including pipe diameter and pressure requirements.
Q4: Are there industry standards for fire demand calculation?
A: Yes, organizations like NFPA (National Fire Protection Association) provide standards and guidelines for calculating fire demand based on various factors.
Q5: How does this calculation apply to real-world scenarios?
A: This calculation helps engineers design water supply systems that can adequately support firefighting operations while maintaining other water supply needs.
