In the planning stage, the difference between available pressure and pressure loss (variation A) in the calculation of pressure loss for each flow path can only amount to 100 mbar.
Positive and negative variations across the respective flow paths should more or less cancel each other out in total.

Example:
In a Siphonic system the flow pathes 1-0, 2-0, 3-0 shall have approximately the same friction loss.
