1. What is Ft³/s to GPM Conversion?

The Ft³/s to GPM conversion calculates flow rate from cubic feet per second to gallons per minute. This conversion is essential in fluid dynamics, hydraulics, and various engineering applications where flow rates need to be expressed in different units.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( ft³/s \) — Flow rate in cubic feet per second
• \( GPM \) — Flow rate in gallons per minute
• \( 448.8311688312 \) — Conversion factor

Explanation: One cubic foot per second equals approximately 448.83 gallons per minute, based on the standard conversion between volume units over time.

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for engineering design, hydraulic calculations, water supply systems, irrigation planning, and industrial processes where different measurement systems are used.

4. Using the Calculator

Tips: Enter the flow rate in cubic feet per second (ft³/s). The value must be non-negative. The calculator will instantly convert it to gallons per minute (GPM).

5. Frequently Asked Questions (FAQ)

Q1: Why is the conversion factor 448.8311688312?
A: This factor comes from the relationship: 1 cubic foot = 7.48051948 gallons and 1 minute = 60 seconds, so 1 ft³/s = 7.48051948 × 60 = 448.8311688 GPM.

Q2: What are typical flow rates in ft³/s?
A: Small streams might flow at 1-10 ft³/s, while major rivers can exceed 1,000 ft³/s. Household water supply typically uses GPM measurements.

Q3: When is this conversion most commonly used?
A: Commonly used in civil engineering, hydrology, water resource management, and plumbing systems where different units are standard in various contexts.

Q4: Are there limitations to this conversion?
A: The conversion is mathematically exact for volume flow rates. However, ensure you're converting volume flow rates, not mass or other types of flow rates.

Q5: Can I convert GPM back to ft³/s?
A: Yes, use the inverse: ft³/s = GPM ÷ 448.8311688312.
