What Is This Tool?
This tool converts flow measurements from acre-foot per day, a volume delivered over a day across an acre area, into gallons (US) per second, representing liquid flow every second. It supports water resource management, agricultural irrigation, and industrial water handling tasks.
How to Use This Tool?
-
Enter the flow value in acre-foot per day
-
Select 'acre-foot/day [ac*ft/d]' as the source unit
-
Choose 'gallon (US)/second' as the target unit
-
Click convert to view the result in gallons per second
-
Use the converted value for irrigation, fire-fighting, or industrial flow calculations
Key Features
-
Converts acre-foot/day to gallon (US)/second accurately using a defined rate
-
Supports volumetric flow measurements vital to water and industrial engineering
-
Provides quick translation of daily flow to per-second flow rates
-
Browser-based access requiring no installation
-
Useful for pump design, monitoring, and operational controls
Examples
-
2 acre-foot/day equals 7.5428873144 gallon (US)/second
-
0.5 acre-foot/day converts to 1.8857218286 gallon (US)/second
Common Use Cases
-
Setting irrigation delivery rates for agricultural water management
-
Reporting inflows and outflows in reservoirs or rivers
-
Sizing municipal or industrial water withdrawals
-
Specifying water pump discharge capacities for firefighting
-
Measuring flow in irrigation and industrial plumbing systems
Tips & Best Practices
-
Always verify unit selections before converting
-
Use this tool to translate average daily flow into instantaneous flow effectively
-
Apply converted values carefully in time-sensitive engineering applications
-
Cross-check conversion results when precise accuracy is critical
-
Consider the context of flow variability when interpreting results
Limitations
-
Acre-foot/day measures average daily volume, which may not reflect short-term changes
-
Gallon (US)/second indicates instantaneous flow rate; the two units differ in temporal meaning
-
Conversion results can be affected by rounding and should be used with caution in detailed engineering
-
This tool does not account for flow fluctuations or transient conditions
-
Ensure suitable application of the converted flow rate depending on system demands
Frequently Asked Questions
-
What does acre-foot per day represent?
-
It measures the volume of water delivered or removed over one day across an area of one acre at a depth of one foot.
-
Why convert acre-foot/day to gallon (US)/second?
-
Converting to gallons per second helps in designing pumps and monitoring flow rates in irrigation and industrial systems.
-
Can this conversion reflect instantaneous flow accurately?
-
No, because acre-foot/day is an average daily flow and may not capture short-term flow variations.
Key Terminology
-
Acre-foot/day [ac*ft/d]
-
A flow rate unit equaling one acre-foot volume delivered or removed per day, used in water resources and hydraulic engineering.
-
Gallon (US)/second
-
A volumetric flow unit representing one U.S. liquid gallon passing a point every second.
-
Volumetric Flow Rate
-
The volume of fluid that passes through a surface per unit time.
