Pressure Drop Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
Formel
ΔP = f × (L/D) × (ρV²/2) using Darcy-Weisbach
Trinn-for-trinn guide
- 1Determine friction factor, pipe length, diameter, and flow velocity
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Løste eksempler
Inndata
100 ft of 1 inch pipe, 5 fps, water
Resultat
ΔP ≈ 4.3 PSI per 100 feet
Vanlige feil å unngå
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
