Cfm To Gpm Formula:
| From: | To: |
The Cfm To Gpm conversion calculates gallons per minute (GPM) from cubic feet per minute (CFM) for water flow rate approximation. This conversion is useful in various fluid dynamics and engineering applications.
The calculator uses the conversion formula:
Where:
Explanation: The formula converts volume flow rate from cubic feet to gallons using the standard conversion factor, then divides by the time factor to get the rate per minute.
Details: Accurate flow rate conversion is essential for designing and analyzing fluid systems, pump selection, pipe sizing, and various engineering calculations in water distribution and HVAC systems.
Tips: Enter CFM value in cubic feet per minute and time factor in minutes. All values must be valid positive numbers.
Q1: Why is 7.48 used as the conversion factor?
A: 7.48 is the number of gallons in one cubic foot of water, making it the standard conversion factor between these units.
Q2: Is this conversion specific to water?
A: Yes, this conversion uses the specific density of water. For other fluids, different conversion factors would be needed based on their density.
Q3: What are typical CFM values in practical applications?
A: CFM values vary widely depending on the application, from small ventilation systems (50-500 CFM) to large industrial fans (10,000+ CFM).
Q4: How accurate is this conversion?
A: The conversion is mathematically precise for volume conversion, but actual flow rates may vary based on system conditions, temperature, and pressure.
Q5: Can this calculator be used for air flow conversion?
A: No, this conversion is specifically for water. Air flow conversion requires different calculations based on air density and specific application requirements.
