What Is This Tool?
This converter transforms volumetric flow rates from acre-foot per day, a measure of daily water volume across an acre, into cubic yard per second, a rate expressing fluid volume passing a point each second in U.S. customary units.
How to Use This Tool?
-
Enter the flow value in acre-foot per day units.
-
Select acre-foot/day as the source unit.
-
Choose cubic yard/second as the target unit.
-
Activate the conversion to obtain the equivalent flow in yd³/s.
Key Features
-
Converts acre-foot/day flow rates, commonly used in irrigation and reservoir management, to cubic yard/second, suited for hydraulic engineering.
-
Supports water-resources planning by translating daily water delivery volumes into instantaneous flow rates.
-
Provides precise conversion factor for accurate unit translation in engineering contexts.
Examples
-
Converting 5 acre-foot/day results in 0.093364571 yd³/s.
-
Converting 10 acre-foot/day results in 0.186729142 yd³/s.
Common Use Cases
-
Defining irrigation delivery rates for agricultural water management.
-
Reporting reservoir or river inflow and outflow in water-resources projects.
-
Sizing municipal or industrial surface water withdrawals and transfers.
-
Expressing river or stream discharge for hydraulic engineering in U.S. customary units.
-
Designing open-channel conveyance and stormwater drainage systems.
-
Specifying flow rates for large pump stations or irrigation canals.
Tips & Best Practices
-
Ensure the flow is steady and uniformly distributed over the time interval before using this conversion.
-
Verify that the temporal context matches: use acre-foot/day for daily volumes and cubic yard/second for instantaneous rates.
-
Cross-check conversion calculations when applying to different hydraulic engineering scenarios.
Limitations
-
Assumes steady, uniform flow conditions and may not apply accurately under transient or variable flows.
-
Not suitable for direct comparison of daily volume units with instantaneous flow rates without contextual consideration.
Frequently Asked Questions
-
What does one acre-foot/day represent?
-
It represents a volumetric flow rate delivering one acre-foot of water volume each day, corresponding to an acre area covered by one foot depth daily.
-
Why convert acre-foot/day to cubic yard/second?
-
Converting these units helps express water flow in a format compatible with hydraulic engineering, which often uses cubic yards per second for instantaneous flow rates.
-
Can this conversion be used for varying flow conditions?
-
No, this conversion assumes steady, uniform flow and may not accurately represent transient or rapidly changing flow conditions.
Key Terminology
-
Acre-foot per day [ac*ft/d]
-
A volumetric flow unit representing one acre-foot of water volume delivered or removed each day, commonly used in water resource management.
-
Cubic yard per second [yd³/s]
-
A volumetric flow unit indicating one cubic yard of fluid passes a point every second, used in U.S. customary hydraulic engineering.
-
Volumetric flow rate
-
A measurement of the volume of fluid passing through a given surface per unit time.
