如何计算Pipe Flow Rate

learn.whatIsHeading

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

公式

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

分步指南

  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

例题解析

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

常见错误注意事项

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