Pump Head Calculator (TDH) — Friction + Static

How do I calculate pump head for a hydronic circulator?

Total dynamic head is the sum of pipe friction, fitting friction, static elevation change, and terminal-device pressure drop. This calculator computes pipe and fitting losses with the Hazen-Williams head-loss method and the ASHRAE equivalent-length approach for fittings, adds elevation directly, and converts the terminal psi drop to feet at 0.4332 psi per foot. The result is the design point you plot against a pump curve.
