What Is This Tool?
This unit converter helps you transform flow measurements from acre-foot per year, a volumetric flow rate used mainly in water resource planning, to liter per second, a unit common in engineering and laboratory flow rate measurements.
How to Use This Tool?
-
Enter the flow value in acre-foot per year you wish to convert.
-
Select acre-foot/year as the from unit and liter/second as the to unit.
-
Click the convert button to get the equivalent flow rate in liters per second.
Key Features
-
Converts acre-foot/year to liter/second with a precise rate.
-
Useful for translating long-term flow rates into instantaneous flow values.
-
Supports applications in water-resources management, irrigation, urban water supply, and HVAC design.
-
Provides easy-to-understand examples for quick reference.
Examples
-
Convert 5 acre-foot/year to liters per second: 5 × 0.0391136089 = 0.195568 L/s.
-
Convert 10 acre-foot/year to liters per second: 10 × 0.0391136089 = 0.391136 L/s.
Common Use Cases
-
Water-resources planning and reservoir yield calculations.
-
Allocating irrigation water rights in agricultural districts.
-
Regional water supply accounting and demand forecasting.
-
Measuring domestic water flow from taps and plumbing fixtures.
-
Specifying flow rates for pumps and dosing equipment in labs.
-
Estimating ventilation or air supply in HVAC systems.
Tips & Best Practices
-
Ensure the flow is relatively uniform throughout the year when applying this conversion.
-
Use this converter to translate long-term water volumes into usable instantaneous flow rates.
-
Verify unit selections before conversions to avoid errors.
-
Apply the tool for both engineering and laboratory flow rate assessments.
Limitations
-
Acre-foot/year measures an annual volume flow rate, so converting to liters per second assumes a steady flow over the whole year.
-
This assumption might not reflect actual variations or fluctuations in flow conditions.
-
The tool does not account for changes in flow rates over shorter periods.
Frequently Asked Questions
-
What does one acre-foot per year represent?
-
It represents a flow rate equal to one acre-foot of volume delivered or used evenly over one year.
-
Why convert acre-foot/year to liter/second?
-
To translate long-term volumetric flow rates into instantaneous values useful for engineering, laboratory, and small-scale water flow assessments.
-
Can this conversion reflect fluctuating flow rates?
-
No, because it assumes uniform flow over the year, which may differ from actual varying flow conditions.
Key Terminology
-
Acre-foot/year [ac*ft/y]
-
A flow rate representing one acre-foot of volume delivered or used over one year; one acre-foot covers one acre to a depth of one foot.
-
Liter/second [L/s]
-
A unit of volumetric flow rate equal to one litre passing through a cross-section every second.
