1. What is Fire Demand Calculation?

Fire Demand calculation determines the amount of water required to extinguish fires in a given area. It's a critical parameter in water supply system design to ensure adequate water availability for firefighting purposes.

2. How Does the Calculator Work?

The calculator uses the Fire Demand formula:

\[ F = \frac{T - \left( \left( a + b + \frac{10}{24} \right) \times D \right) + \left( \frac{10}{24} \times P \right)}{\frac{10}{24}} \]

Where:

\( F \) — Fire Demand (m³/s)
\( T \) — Total Storage Capacity (m³/s)
\( a \) — Numerical Coefficient a
\( b \) — Numerical Coefficient b
\( D \) — Average Domestic Demand (m³/s)
\( P \) — Capacity of Pump (m³/s)

Explanation: This formula calculates the fire demand by considering total storage capacity, numerical coefficients, average domestic demand, and pump capacity to determine the water required for firefighting.

3. Importance of Fire Demand Calculation

Details: Accurate fire demand calculation is crucial for designing water supply systems that can adequately handle emergency fire situations while maintaining normal domestic water supply.

4. Using the Calculator

Tips: Enter all values in appropriate units (m³/s). Ensure numerical coefficients are accurate for your specific scenario. All values must be non-negative.

5. Frequently Asked Questions (FAQ)

Q1: What are typical values for numerical coefficients a and b?
A: The values of coefficients a and b vary based on local regulations, building types, and fire risk assessment. Consult local fire codes for specific values.

Q2: How is total storage capacity determined?
A: Total storage capacity is based on the maximum volume the water storage system can hold, considering factors like reservoir size, tank capacity, and system design.

Q3: Why is pump capacity important in fire demand calculation?
A: Pump capacity determines how much water can be delivered to firefighting equipment, directly affecting the system's ability to meet fire demand requirements.

Q4: How often should fire demand calculations be updated?
A: Fire demand calculations should be reviewed periodically, especially when there are changes in building density, population, or fire safety regulations.

Q5: Are there different formulas for different types of areas?
A: Yes, fire demand formulas may vary based on urban vs. rural areas, building densities, and specific fire risk factors in different regions.
