Type | Formula |
Pressure | Water Head (Metres) * 0.0981 = Pressure (Bar) |
Water Power | 100*Litres*Pressure | = Water Power(WP)watts | 60 |
|
Nozzle Discharge | 2 d2 √ P | = Nozzle Discharge (LPM) | 3 |
|
Velocity | |
Jet Reaction | |
Extinguishers | (Area * 0.065)/Rating = Total Extinguishers Rating 13 = 9 Ltr Water Rating 34 = 9Kg Dry Powder |
Cube | Width * Length * Height = Area (cubed) |
Square | Width * Length = Area (squared) |
Circle | π = Area (squared) |
No of Persons | Floor Area in meters 2 | = No of Persons | Occupant Load Factor |
|
Units of Exit Width | No of Persons | = No of Units of Exit Width | 40 X Time Factor |
|
No of Exits | No of Units | + 1 = Minimum No of Exits | 4 |
