Population Formula:
Definition: This calculator estimates the population served based on the number of fire streams required simultaneously for firefighting.
Purpose: It helps fire departments and urban planners determine the population coverage based on firefighting resource requirements.
The calculator uses the formula:
Where:
Explanation: The formula relates the number of fire streams needed to the population size they serve, with a standard coefficient of 2.8.
Details: Proper estimation ensures adequate fire protection coverage and helps in planning fire department resources for different population sizes.
Tips: Enter the number of fire streams required simultaneously. The result shows population in thousands (e.g., 20 means 20,000 people).
Q1: What is a fire stream?
A: A fire stream is the flow of water or extinguishing agent from a fire nozzle at required pressure and flow rate.
Q2: Why is there a ±5% variation?
A: The 5% accounts for normal variations in population density and fire risk factors in different areas.
Q3: Where does the 2.8 coefficient come from?
A: It's an empirical factor derived from fire service experience and population studies.
Q4: How accurate is this calculation?
A: It provides a good estimate for planning purposes, but local factors may require adjustments.
Q5: Can this be used for very large populations?
A: The formula works best for populations under 500,000. For larger cities, other factors become more significant.
