如何计算Flow Rate Converter
learn.whatIsHeading
Flow rate converters translate between volumetric (m³/s, L/min, GPM) and mass (kg/s, lb/hr) flow units, accounting for density.
公式
Mass flow (ṁ): kg/s, lb/hr, mass rate = volumetric × density
分步指南
- 1Volumetric flow (Q): m³/s, L/min, GPM, CFM
- 2Mass flow (ṁ): kg/s, lb/hr, mass rate = volumetric × density
- 3Water: ~1 kg/L simplifies; other fluids require density input
例题解析
输入
100 L/min water flow
结果
1.67 L/s, 100 kg/min, 26.4 GPM
Water density ~1 kg/L
常见错误注意事项
- ✕Confusing volumetric and mass flow without accounting for density
- ✕Using wrong density (temperature/pressure dependent)
常见问题
When do you use mass vs. volumetric flow?
Volumetric for pipe sizing, volume-based charges. Mass for energy balance, combustion calculations.
Does flow rate change with pressure?
Incompressible liquids: no. Compressible gases: yes, density varies with pressure.
