如何计算Pipe Volume

learn.whatIsHeading

A pipe volume calculator finds the internal fluid volume of a cylindrical pipe from its inner diameter and length. Used in plumbing, HVAC, and chemical engineering.

公式

Volume = π × (d/2)² × length | Use inner diameter | Convert m³ to litres: × 1,000

d: Inner diameter (m)
L: Pipe length (m)
V: Volume (m³)

分步指南

1Volume = π × (d/2)² × length
2Use inner diameter, not outer
3Keep units consistent (all metres)
4Multiply m³ × 1,000 for litres

例题解析

输入

Inner diameter 5cm, length 8m

结果

V = π × 0.025² × 8 = 0.01571 m³ = 15.71 litres
