Volume Flow Rate vs Fluid Velocity (V)
Formel
## Volumetric Flow Rate Volumetric flow rate is the volume of fluid passing through a cross-section per unit time. It is widely used in piping design, pump selection, and flow measurement. ### Formula **Q = V × A = V × pi × D² / 4** where V is the average fluid velocity and A is the pipe cross-sectional area. Different industries use different units: m³/h in process, L/min in hydraulics, GPM in plumbing.
Lösungsbeispiel
Water flowing at 3 m/s through a 150 mm pipe.
- 01D = 150 mm = 0.15 m
- 02A = pi × 0.15² / 4 = 0.01767 m²
- 03Q = 3 × 0.01767 = 0.05301 m³/s
- 04Q = 0.05301 × 60000 = 3180.9 L/min
- 05Q = 0.05301 × 15850.3 = 840.2 GPM
Häufig Gestellte Fragen
How do I convert between GPM and m³/h?
1 GPM = 0.2271 m³/h, or 1 m³/h = 4.403 GPM. Multiply GPM by 0.2271 to get m³/h, or multiply m³/h by 4.403 to get GPM.
Does volumetric flow change with temperature?
For liquids, the change is usually small (water expands about 4% from 20°C to 80°C). For gases, volumetric flow changes significantly with temperature and pressure. This is why gas flows are often stated at standard conditions (STP or NTP).
What is normal vs actual volumetric flow for gases?
Normal flow (Nm³/h) is referenced to standard conditions (0°C, 1 atm). Actual flow is at operating conditions. Convert using the ideal gas law: Q_actual = Q_normal × (T_actual/T_normal) × (P_normal/P_actual).
