Quantity of Water by Buston's Formula Calculator

Buston's Formula:

\[ Q = 5663 \times \sqrt{P} \]

Water Quantity (L/min):

1. What is Buston's Formula for Water Quantity?

Definition: Buston's formula calculates the quantity of water required to extinguish fires based on the population of the affected area.

Purpose: It helps fire departments and emergency planners determine water requirements for firefighting in different areas.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = 5663 \times \sqrt{P} \]

Where:

\( Q \) — Quantity of water in liters per minute
\( P \) — Population in thousands (e.g., 20,000 people = 20)

Explanation: The formula relates water requirement to the square root of population, with a constant factor of 5663.

3. Importance of Water Quantity Calculation

Details: Accurate water quantity estimation ensures adequate firefighting resources, proper infrastructure planning, and community safety.

4. Using the Calculator

Tips: Enter the population in thousands (e.g., for 25,000 people enter 25). The result has a ±5% margin of error.

5. Frequently Asked Questions (FAQ)

Q1: Why does the formula use square root of population?
A: The square root relationship accounts for the fact that fire risk doesn't increase linearly with population density.

Q2: What does the ±5% represent?
A: It accounts for variations in local conditions, building types, and other factors affecting water needs.

Q3: Is this formula used worldwide?
A: While commonly used, local regulations may specify different formulas based on regional conditions.

Q4: How accurate is Buston's formula?
A: It provides a good estimate for general planning but should be adjusted for specific local conditions.

Q5: What other factors affect water requirements?
A: Building materials, fire department response time, and water supply infrastructure also play important roles.
