GPM to CFH Conversion Formula:
| From: | To: |
GPM to CFH conversion is used to convert flow rate measurements from gallons per minute (GPM) to cubic feet per hour (CFH). This conversion is commonly used in fluid dynamics, plumbing, irrigation systems, and industrial applications where different units of flow measurement are required.
The calculator uses the conversion formula:
Where:
Explanation: The conversion factor accounts for both volume conversion (gallons to cubic feet) and time conversion (minutes to hours).
Details: Accurate flow rate conversion is essential for system design, pump selection, pipe sizing, and ensuring compatibility between different measurement systems used in various industries and applications.
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 hour (CFH).
Q1: Why is the conversion factor 8.020833333333333?
A: This factor comes from multiplying the gallon to cubic foot conversion (1 gallon = 0.133680556 ft³) by the minutes to hours conversion (60 minutes = 1 hour): 0.133680556 × 60 = 8.020833333333333.
Q2: When would I need to convert GPM to CFH?
A: Common applications include HVAC system design, water treatment plants, fire protection systems, and industrial processes where different units are used for flow measurement.
Q3: What is the typical range for GPM values?
A: Residential water systems typically range from 2-10 GPM, while industrial applications can range from 10 to several thousand GPM.
Q4: Are there any limitations to this conversion?
A: This conversion assumes standard temperature and pressure conditions. For precise engineering applications, specific gravity and temperature corrections may be needed.
Q5: Can this conversion be used for gases as well as liquids?
A: While the mathematical conversion is the same, gas flow rates are often measured differently due to compressibility factors. This conversion is primarily used for liquids.
