What Is This Tool?
This tool converts volumetric flow rates from hundred-cubic foot/hour to cubic yard/second [yd³/s], enabling users to translate low to moderate gas or air flow rates into units commonly used in hydraulic and water resource engineering.
How to Use This Tool?
-
Enter the flow rate value in hundred-cubic foot/hour.
-
Select the source unit as hundred-cubic foot/hour and the target unit as cubic yard/second [yd³/s].
-
Press the convert button to obtain the equivalent flow rate in cubic yard/second.
Key Features
-
Converts flow rates between hundred-cubic foot/hour and cubic yard/second accurately.
-
Supports measurements relevant to natural gas utilities, HVAC, civil engineering, and water management.
-
Browser-based and easy to use without requiring software installation.
Examples
-
100 hundred-cubic foot/hour equals 0.10288066 cubic yard/second [yd³/s].
-
50 hundred-cubic foot/hour equals 0.05144033 cubic yard/second [yd³/s].
Common Use Cases
-
Utility reporting of natural gas consumption for residential and small commercial users.
-
Sizing and monitoring gas supplies to appliances, burners, or pilot lines.
-
Specifying ventilation and exhaust rates in imperial units.
-
Expressing river discharge and flood flow rates in U.S. customary units.
-
Designing open-channel conveyance and stormwater drainage systems.
-
Specifying pump or irrigation canal flow rates in civil water projects.
Tips & Best Practices
-
Ensure steady flow conditions when applying the conversion for accurate results.
-
Be aware of the unit scale difference—values may become very small after conversion.
-
Consider temperature, pressure, and fluid properties if precise measurements are required.
Limitations
-
Conversion assumes steady flow and standard conditions; gas composition or fluid changes may affect accuracy.
-
Measurement precision is important due to the disparity in scale between the two units.
Frequently Asked Questions
-
What does hundred-cubic foot/hour measure?
-
It measures a volumetric flow where 100 cubic feet of gas or air pass a point each hour, often used in utility and appliance flow measurements.
-
Where is cubic yard/second commonly used?
-
It is used in U.S. customary engineering fields like hydraulics and water resources to express large flow rates such as river discharge and irrigation canal flow.
-
Can this conversion be used for gases and liquids alike?
-
The conversion is for volumetric flow rates; however, variations in fluid properties and conditions may require adjustments beyond this conversion.
Key Terminology
-
Hundred-cubic foot/hour
-
A flow rate unit indicating 100 cubic feet of gas or air passing a point in one hour, used for low-to-moderate flow measurements.
-
Cubic yard/second [yd³/s]
-
A volumetric flow unit representing one cubic yard of fluid passing a point every second, common in hydraulic engineering.
-
Volumetric flow rate
-
The quantity of fluid volume passing through a surface per unit of time.
