Field notes

The catalog includes specialized methods and conversions, including pressure loss using Darcy-Weisbach and Colebrook-White, and water balance calculations referencing IWA. Its conversion list distinguishes US from UK gallons and includes trade-oriented units such as gpm, psi, and grains per gallon. The homepage also links to a chain-calculator editor, though its operation is not shown in the extracted material.
