Lt = Ls + ΣLe — fittings data from project.
Sums straight length + equivalent length of fittings. Fitting Le values must come from project data / manufacturer charts — this tool does not invent K or Le/D tables.
Feed Lt into Hazen–Williams or Darcy–Weisbach length inputs for friction-only estimates that include fittings via equivalent length.
What it calculates: Equivalent length calculator results for preliminary design discussion. Outputs are educational aids — validate against project codes and manufacturer data before construction.
Converts fittings into equivalent straight-pipe length for approximate friction-loss budgets.
Fitting equivalent lengths (from tables) and pipe diameter. Values are assumptions unless taken from a cited table.
Minor-loss coefficients (K) methods may be preferable for detailed design. Confirm fitting geometry with the project.
