1. What is CFS to GPD Conversion?

The CFS to GPD conversion calculates flow rate from cubic feet per second to gallons per day. This conversion is essential in hydraulic engineering, water resource management, and environmental studies where flow rates need to be expressed in different units for various applications.

2. How Does the Calculator Work?

The calculator uses the conversion formula:

Where:

• \( GPD \) — Gallons per day
• \( CFS \) — Cubic feet per second
• \( 646316.8831169279 \) — Conversion factor

Explanation: The conversion factor is derived from the relationship between cubic feet and gallons (1 ft³ = 7.48052 gallons) and seconds to days (1 day = 86400 seconds).

3. Importance of Flow Rate Conversion

Details: Accurate flow rate conversion is crucial for water supply planning, irrigation system design, wastewater treatment, and hydraulic calculations in civil and environmental engineering projects.

4. Using the Calculator

Tips: Enter the flow rate in cubic feet per second (CFS). The value must be non-negative. The calculator will automatically compute the equivalent flow rate in gallons per day (GPD).

5. Frequently Asked Questions (FAQ)

Q1: What is the exact conversion factor?
A: The precise conversion factor is 646316.8831169279 gallons per day per cubic foot per second.

Q2: Why is this conversion important?
A: Different industries use different units - CFS is common in engineering, while GPD is often used in water supply and treatment applications.

Q3: How accurate is this conversion?
A: The conversion is mathematically exact based on standard unit definitions, with precision up to 10 decimal places.

Q4: Can this be used for any fluid?
A: This specific conversion is designed for water. For other fluids, density corrections may be necessary.

Q5: What are typical CFS values in practice?
A: Small streams might flow at 1-10 CFS, while major rivers can exceed 10,000 CFS during flood conditions.
