Flow Rate Conversion Relationship
The flow rate in cubic feet per second (CFS) can be converted from gallons per minute (GPM) using the following formula:
CFS = GPM × 0.00222800926
Flow Rate Input:
Flow rate measures the volume of fluid passing through a point per unit time. Common units include:
- GPM (Gallons per Minute): Standard in the US for water flow.
- GPH (Gallons per Hour): Used for slower flow systems.
- L/min (Liters per Minute): Metric unit for medium flows.
- L/s (Liters per Second): Metric unit for high flows.
- L/h (Liters per Hour): Metric unit for low flows.
- m³/h (Cubic Meters per Hour): Common in industrial settings.
- m³/s (Cubic Meters per Second): For large-scale flows.
- CFS (Cubic Feet per Second): Used in hydrology and river flow.
- CFM (Cubic Feet per Minute): Common in HVAC systems.
Practical Applications
This converter is useful in various scenarios:
- Hydrology: Convert GPM from pumps to CFS for river or stream flow analysis.
- Irrigation: Standardize flow rates between imperial and metric units.
- Engineering: Compare pump outputs in CFS with HVAC requirements in CFM.
Example Calculation
If the flow rate is 100 GPM, the conversion to CFS would be:
CFS = 100 × 0.00222800926 = 0.2228 \, \text{ft³/s}
Similarly:
- CFM = 0.2228 × 60 = 13.368 ft³/min
- GPH = 0.2228 × 448.8311688 = 100 GPH
- m³/s = 0.2228 × 0.028316846592 = 0.00631 m³/s
- L/s = 0.2228 × 28.316846592 = 6.31 L/s
Conversion Constants
Key conversion factors:
- 1 Gallon = 0.1336805556 ft³
- 1 ft³ = 28.316846592 Liters
- 1 ft³ = 0.028316846592 m³
- 1 minute = 60 seconds
- 1 hour = 3600 seconds
