Pipe Sizing Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.
Formel
Min Diameter = √(4Q / π × V) where Q=flow, V=max velocity
Steg-för-steg-guide
- 1Determine required flow rate, select acceptable velocity, solve for diameter
- 2Apply the formula using your project measurements
- 3Add required safety factors or waste allowances per code
Lösta exempel
Ingång
50 GPM flow, 6 fps max velocity
Resultat
D = √(4×0.111/(π×6)) = 0.154 ft = 1.85 inches → use 2 inch
Vanliga misstag att undvika
- ✕Not applying code-required safety factors or derating
- ✕Forgetting to account for waste and cut losses in material estimates
