1. What is a Volumetric Flow to Velocity Calculator?

Definition: This calculator converts volumetric flow rate to fluid velocity based on the cross-sectional area of flow.

Purpose: It helps engineers and technicians determine fluid velocity in pipes or channels when the flow rate is known.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( V \) — Velocity (feet per second)
• \( Q \) — Volumetric flow rate (gallons per minute)
• \( A \) — Cross-sectional area (square feet)
• \( 448.83 \) — Conversion factor (GPM to ft³/s)

Explanation: The flow rate is divided by the area and conversion factor to get velocity in consistent units.

3. Importance of Velocity Calculation

Details: Proper velocity calculation ensures efficient system design, prevents erosion, and maintains optimal flow conditions.

4. Using the Calculator

Tips: Enter the flow rate in GPM and cross-sectional area in square feet. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the 448.83 conversion factor?
A: It converts gallons per minute to cubic feet per second (1 GPM = 0.002228 ft³/s, inverse is 448.83).

Q2: What's a typical velocity range for water in pipes?
A: Typically 2-5 ft/s for water supply, up to 10 ft/s for drainage systems.

Q3: Can I use this for other fluids?
A: Yes, but the calculator assumes similar density to water. For viscous fluids, additional factors may be needed.

Q4: How do I find the cross-sectional area?
A: For circular pipes, A = π × (diameter/2)². For rectangular channels, A = width × height.

Q5: What if my area is in inches?
A: Convert to square feet first (1 ft² = 144 in²) before using the calculator.
