Number of aspiration apertures = total number of aspiration apertures of the respective branch
* number of branches in the pipe system
Calculation
The diameters of the aspiration apertures for an asymmetrical U
‑
pipe system
are determined as specified below:
The result and the table of the corresponding pipe shape of the pipe system
yield the individual diameters of the aspiration apertures for the respective
branch (see chapter "Determining the diameter of the aspiration apertures").

Determining the number of aspiration apertures for a long branch
Image 41:
Determining the number of aspiration apertures for a short branch
The diameters of the aspiration apertures for an asymmetrical U
‑
pipe system
(two branches) should be determined. The short branch comprises three
aspiration apertures and the long branch comprises six aspiration apertures.
The number of aspiration apertures must be multiplied with the number of
branches of the pipe system in each case. From the U-pipe systems table,
the diameter of the aspiration apertures of column "6" must be taken for the
short branch and of column "12" for the long branch (see figure "Examples of
symmetrical and asymmetrical U-pipe system").
Branch length
In order to ensure a short transport time for the smoke aerosols in the
aspiration pipe and thus enable rapid detection, it is better to plan several
shorter branches than a few long ones (preferably a U- or double U-pipe
system).
