Fire Flow Calculation - based on Underwriters Guide, 1999
167, 169, 171 Island Highway, View Royal, BC
Type of Construction:
- C = 1.5: Wood Frame - structure essentially all combustible
- C = 1.0: Brick or masonry walls - ordinary construction
- C = 0.8: Unprotected metal structural components - non combustible
- C = 0.6: Fully protected frame, floor, roof - fire resistive
C = 1.30 (Note: Reduce 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
The Estimated Fire-Flow above can potentially be reduced as follows:
Occupancy:
| Occupancy Type | % |
|---|---|
| Non-combustible | -25 |
| Limited Combustible | -15 |
| Combustible | 0 |
| Free burning | 15 |
| Rapid burning | 25 |
- 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:
| Protection Level | % |
|---|---|
| Fully automated sprinklers | -50 |
| -40 | |
| -30 | |
| No sprinklers | 0 |
- 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 mille 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
Calculation Summary
- Estimated Fire-Flow (with reductions & charges): F = 170.6 L/s
- TOTAL FUS FIRE-FLOW COVERAGE REQUIRED: F = 170.6 L/s
- Conversion: 10237.5 L/min
