Type of Construction
| Coefficient (C) | Construction Description |
|---|---|
| 1.5 | Wood Frame - structure essentially all combustible |
| 1 | Brick or masonry walls - ordinary construction |
| 0.8 | Unprotected metal structural components - non combustible |
| 0.6 | Fully protected frame, floor, roof - fire resistive |
| 1.30 | Selected Coefficient (Reduced for non-combustible siding and roofing) |
Finished Floor area
- A = 5567 sq.m (59920 sq.ft)
Estimated Fire-Flow
- F = 220 * C * (A^1/2)
- F = 21339 L/min
- F = 21000 L/min (Rounded to nearest 1000)
- F = 350.0 L/s
Reductions and Charges
Occupancy
The Estimated Fire-Flow above can potentially be reduced as follows:
| % | Occupancy Type |
|---|---|
| -25 | Non-combustible |
| -15 | Limited Combustible |
| 0 | Combustible |
| 15 | Free burning |
| 25 | Rapid burning |
- Selected: -25%
- Amount of Fire-Flow reduction (Occupancy): F = -87.5 L/s
- Estimated Reduced Fire-Flow (Occupancy): F = 262.5 L/s
Sprinkler Protection
| % | Sprinkler Type |
|---|---|
| -50 | Fully automated sprinklers |
| -40 | |
| -30 | |
| 0 | No sprinklers |
- Selected: -50%
- Amount of Fire-Flow reduction (Sprinkler): F = -131.3 L/s
Exposure Separation
| # of sides | Separation | Charge % | Location Description |
|---|---|---|---|
| 0 | 0 - 3 meters | 0 | |
| 0 | 3.1 - 10 | 0 | |
| 0 | 10.1 - 20 | 0 | |
| 1 | 20.1 - 30 | 10 | Six mile pub to the west |
| 1 | 30.1 - 45 | 5 | View Royal municipal hall to the south and house across the road to the north |
| 2 | 45 - | 0 | park to the east |
| 4 | 15% | (75% max) |
- Exposure Separation charge: F = 39.4 L/s
Final Calculation
- Estimated Fire-Flow (with reductions & charges): F = 170.6 L/s
TOTAL FUS FIRE-FLOW COVERAGE REQUIRED
- F = 170.6 L/s (10237.5 L/min)
