Water Hammer Calculator

Calculate water hammer pressure surge: ΔP = ρ·a·ΔV (Joukowski), wave speed a = √(K/ρ)/√(1+K·D/(E·t)). Critical closure time T_c = 2L/a. Surge protection with air vessels and relief valves.

2D stress state at a point. All stresses in MPa.

σx — Normal Stress X (MPa)
σy — Normal Stress Y (MPa)
τxy — Shear Stress (MPa)
⚙ Mechanical Note: Results are based on standard textbook formulas and ISO/AASHTO references. Always verify critical designs with applicable codes (ISO 898, AASHTO 1993, AISC, Eurocode 3) and a qualified engineer.
