Pipe Flow Rate Calculator helps contractors and tradespeople accurately size, spec, and estimate materials and systems.

Fórmula

Q = A × V where A = pipe cross-section area, V = fluid velocity

Guia passo a passo

  1. 1Measure pipe diameter, estimate or measure flow velocity
  2. 2Apply the formula using your project measurements
  3. 3Add required safety factors or waste allowances per code

Exemplos resolvidos

Entrada
2 inch pipe (A=0.0218 sf), 5 fps velocity
Resultado
Q = 0.0218 × 5 = 0.109 cfs = 49 GPM

Erros comuns a evitar

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