PDP= NP + FL +/- H

PDP=Pump Discharge Pressure

NP=Nozzle Pressure

FL=Friction Loss

H=Head Pressure

FL=CQ^2L in kPa

FL=Friction Loss

C=Friction Loss Coefficients

Q=Flow divided by 100

L=is equal to the number 30 m lengths

Approx. Fire Flow requirements for a structure fire=l*w*h*1.3

L=length of the building

W=width of the building

H=Height of the building

1.3=constant
