Water Hammer Pressure Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

Formel

Surge Pressure = ρ × a × V / g where a=wave speed, V=velocity change

Trin-for-trin guide

  1. 1Calculate wave speed, multiply by velocity change and density
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

Løste eksempler

Input
V=5 fps change, a=4000 fps wave speed
Resultat
Surge = (62.4 × 4000 × 5) / (32.2 × 144) = 269 PSI

Almindelige fejl at undgå

  • Not applying code-required safety factors or derating
  • Forgetting to account for waste and cut losses in material estimates
