Flow

Definition

The movement of water through a system, one of the two governing conditions (with heat) that drive all four pillars.

Flow and heat are listed as the conditions that govern scale, corrosion, biology, and solids. Stagnant or low-flow zones favor deposition, biofilm, and under-deposit corrosion, while flow distributes chemistry and heat. It is part of the hydraulics that form the architectural framework of the discipline. The free body diagram accounts for it as a force-shaping condition.
