1.7.4 Dimensioning of pipe systems
The below diagram shows the current pressure drop graphs meant for the dimensioning
of pipe systems used in connection with the
DELTABOOSTER plant.
The diagram illustrates two vertical divisions for
II
) electro galvanized steel pipes 15x2 mm - 22x2.5 mm - 30x4 mm
I
) stainless steel pipes 15x1.5 mm - 22x2 mm - 30x3 mm
The pressure drop per metre of pipe at a given water volume may be read from the fol-
lowing pressure drop graph.
When dimensioning the system be careful that the maximum pressure drop at the remotest
outlet point does not exceed 15 bar at full load.
The pressure drop in elbows and branches is of minor importance in relation to the pressure
drop in the pipes.
