What Is This Tool?

This tool enables you to convert volumetric flow rates from gallon (US) per minute to acre-foot per year, facilitating translation between short-term flow measures and annual volume rates used in water resource management and irrigation planning.

How to Use This Tool?

Enter the flow rate in gallons (US) per minute.
Select gallon (US)/minute as the input unit.
Choose acre-foot per year [ac*ft/y] as the output unit.
Click the convert button to see the equivalent flow rate.
Use the results for water resource planning or irrigation management.

Key Features

Converts US liquid gallons per minute to acre-foot per year accurately.
Supports applications in plumbing, HVAC, irrigation, and municipal water supply.
Browser-based and easy to use with straightforward input and output.
Provides relevant conversion rate and example calculations.
Assists with long-term water resource and agricultural management.

Examples

Convert 5 gallon (US)/minute to acre-foot/year results in about 8.065 ac*ft/y.
Convert 10 gallon (US)/minute to acre-foot/year results in about 16.13 ac*ft/y.
Use the conversion formula: 1 gallon (US)/minute equals 1.6129985985 acre-foot/year.

Common Use Cases

Specifying pump capacities and sprinkler flow rates for residential and commercial plumbing.
Rating water flow in HVAC systems and cooling tower circulation.
Translating short-term flow rates to annual volumes for water resource planning.
Allocating surface water and irrigation rights in agriculture.
Performing municipal and regional water supply accounting and demand forecasts.

Tips & Best Practices

Ensure input values represent steady and continuous flow conditions.
Consider the time scale differences when comparing flow rates (per minute vs. per year).
Use this tool for planning and accounting rather than real-time dynamic flow analysis.
Verify flow rates with local water resource parameters when applying results.

Limitations

The units measure flow over different time intervals, which may affect interpretations.
Conversion assumes continuous flow, not accounting for intermittent or variable conditions.
Dynamic systems with fluctuating flow require more detailed analysis beyond this conversion.
