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	Distance =Velocity Time
Jet Reaction	1.57 P d2 =Jet Reaction 10
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	= 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
