Step 4: Check of the pressure loss
The pressure loss at the extraction point with the larg-
est distance to the supply unit should not exceed 15%.
For the calculation, the fittings are replaced by a
straight pipe segment with the same stream resist-
ance. The values for this can be taken from Table 4.
The pipe length can be used to determine the pres-
sure loss from diagram 2.
