FIRE FLOW CALCULATION SHEET
1.
- Type of Construction: WOOD
- Co-efficient (C) based on type of construction = 1.5
- Ground Floor Area: 130 sq.m.
- No. of Stories = 2
- Total Floor Area: 200 sq.m.
- Fire Flow Formula (F=220C(A)1/2): 4667 L/min = 78 L/sec (a)
2.
- Type of Occupancy: SFD
- Hazard: Low X High ___ Other ___
- Hazard Allowance: Add or subtract 0
- % x (a) = ___
- Sub Total: ___ L/sec (b)
3.
- Automatic Sprinklers: N (yes/no)
- Sprinkler Allowance: Subtract (max 50%): ___ % x (b) = 0 L/sec (c)
- Sub Total: 0 L/sec (d)
4.
Exposures: Distance/ Hazard (meters)
- Front: >45 m Add ___ %
- Left: <3 m Add 25 %
- Rear: >45 m Add ___ %
- Right: <3 m Add 25 %
- Exposure Allowance (max 75%): Add 50 (e) % x (b) = 39 L/sec (f)
Totals
TOTAL FIRE FLOW REQUIRED: 117 L/sec (g)
REQUIRED PRESSURE: 138 kPa
AVAILABLE FIRE FLOW (@ 138 kPa): ___ L/sec (h)
15L/s < 4800 L/min as per CRD Engineering Standards Section 4.2.2.; therefore, USE 4800L/min (81L/s)
Available Flows @ 138kPa
