Detailed Description

Force main friction — Hazen-Williams and Darcy-Weisbach.

Alternative friction models for pressurised pipes. Called by DynamicWave solver when xsect type is FORCE_MAIN.

Both formulas compute friction slope Sf from velocity and hydraulic radius — vectorisable over all force main links.
