Fire Demand Formula:
| From: | To: |
Fire Demand refers to the amount of water required by firefighters to extinguish fires in buildings, structures, or open areas. This calculation is essential for urban planning and water supply system design for cities with populations under 200,000.
The calculator uses the Fire Demand formula:
Where:
Explanation: The formula calculates the required water flow rate for firefighting purposes based on population size, with adjustments for smaller cities.
Details: Accurate fire demand estimation is crucial for designing adequate water supply systems, ensuring sufficient water pressure and volume for firefighting operations, and meeting municipal safety standards.
Tips: Enter population in thousands (actual population divided by 1000). The value must be between 0 and 200 (for cities under 200,000 population).
Q1: Why is this formula specific to cities under 200,000 population?
A: Different population ranges have different fire demand characteristics. This formula is optimized for smaller cities where fire risks and water demand patterns differ from larger metropolitan areas.
Q2: What factors affect fire demand besides population?
A: Building density, construction types, fire department response times, and local fire codes can all influence actual fire water requirements.
Q3: How is this calculation used in urban planning?
A: Planners use fire demand calculations to design water distribution systems, determine pipe sizes, and ensure adequate water storage capacity for emergency firefighting.
Q4: Are there different formulas for different types of areas?
A: Yes, industrial areas, commercial districts, and residential zones may have different fire demand requirements based on fire risk assessments.
Q5: How often should fire demand calculations be updated?
A: Fire demand calculations should be reviewed whenever there are significant population changes, urban development projects, or updates to fire safety regulations.
