Flow Rate Conversion Formula:
| From: | To: |
The GPM to ft³/s conversion calculates flow rate from gallons per minute to cubic feet per second. This conversion is essential in fluid dynamics, hydraulic engineering, and various industrial applications where flow rates need to be expressed in different units.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor is derived from the relationship between gallons and cubic feet, and minutes to seconds (1 gallon = 0.133681 ft³, 1 minute = 60 seconds).
Details: Accurate flow rate conversion is crucial for engineering calculations, pipe sizing, pump selection, and system design in water distribution, HVAC systems, and industrial processes.
Tips: Enter the flow rate in gallons per minute (GPM). The value must be positive. The calculator will automatically convert it to cubic feet per second (ft³/s).
Q1: What is the difference between GPM and ft³/s?
A: GPM measures flow rate in gallons per minute, while ft³/s measures flow rate in cubic feet per second. They are different units for the same physical quantity.
Q2: When would I need to convert between these units?
A: Conversion is needed when working with international standards, different engineering specifications, or when integrating systems that use different unit systems.
Q3: What is the conversion factor based on?
A: The factor comes from: 1 gallon = 0.133681 ft³ and 1 minute = 60 seconds, so 1 GPM = 0.133681/60 = 0.002228 ft³/s.
Q4: Are there any limitations to this conversion?
A: This conversion is exact for water and similar density fluids. For fluids with significantly different densities, additional factors may be needed for mass flow calculations.
Q5: Can I use this for both liquid and gas flow?
A: While the volume conversion is valid, gas flow calculations often require additional considerations for compressibility and temperature effects.
