What Is This Tool?
This converter transforms flow rate measurements in cubic foot per hour (ft^3/h) into gallon (US) per minute (gpm). The tool is useful for engineers, contractors, and technicians who need to translate volumetric flow data between these units, ensuring compatibility across various systems and applications.
How to Use This Tool?
-
Enter the flow value measured in cubic foot per hour.
-
Select cubic foot/hour as the input unit and gallon (US)/minute as the target unit.
-
Click convert to get the equivalent value in gallons per minute.
-
Use the results to interpret or specify pump capacities, piping flows, or fuel rates.
Key Features
-
Converts volumetric flow rates between cubic foot/hour and gallon (US)/minute.
-
Supports common engineering and industrial measurements related to gases and liquids.
-
Provides quick calculations for pump sizing, HVAC airflow, plumbing, and fuel flow tasks.
-
Browser-based tool that requires no installation or registration.
-
Includes example conversions for easy understanding.
Examples
-
5 cubic foot/hour converts to approximately 0.6234 gallon (US)/minute.
-
10 cubic foot/hour equals about 1.2468 gallon (US)/minute.
Common Use Cases
-
Calculating ventilation or exhaust rates in HVAC systems using cubic foot per hour data.
-
Measuring gas flows in pipelines and industrial metering equipment.
-
Sizing pumps, filters, and blowers for low-to-moderate flow systems.
-
Specifying pump capacities and irrigation flow rates in plumbing and sprinkler systems.
-
Determining liquid transfer rates in automotive or fuel handling procedures.
Tips & Best Practices
-
Confirm unit types before converting to avoid errors due to regional differences like US vs. imperial gallons.
-
Use steady flow assumptions as the tool does not adjust for compressibility or temperature influences on volume.
-
Verify if volumetric flow units correspond with system requirements since mass flow conversions need density data.
-
Apply conversions consistently across engineering designs and operational monitoring for accuracy.
Limitations
-
Assumes steady flow without accounting for fluid compressibility or temperature changes.
-
Only converts volumetric flow units and is not suitable for direct mass flow conversions without density information.
-
Usage of US gallons may be confusing in regions using imperial gallons or metric units, requiring careful verification.
Frequently Asked Questions
-
What does cubic foot per hour measure?
-
It indicates the volume of one cubic foot passing through a point in one hour, representing volumetric flow rate of fluids or gases.
-
Where is gallon (US)/minute commonly used?
-
It is used to specify flow rates in pumps, plumbing, irrigation systems, HVAC water circulation, and fuel transfer in many North American applications.
-
Can this conversion account for different fluid temperatures or densities?
-
No, the conversion assumes steady flow and constant conditions, so temperature and density variations are not included.
Key Terminology
-
Cubic foot/hour [ft^3/h]
-
A volumetric flow rate unit measuring the volume of one cubic foot moving past a point in an hour.
-
Gallon (US)/minute
-
A flow rate unit showing the number of US liquid gallons flowing through a point each minute.
-
Volumetric flow rate
-
The measurement of the volume of fluid passing through a cross-section per unit time.
