1. What is the Fill-Rite Flow Meter 800 Series?

Definition: This calculator determines the flow rate (Q) in gallons per minute (GPM) for Fill-Rite 800 series meters based on velocity and cross-sectional area.

Purpose: It helps professionals and technicians calculate fluid flow rates in various industrial and commercial applications.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Q = V \times A \times 448.83 \]

Where:

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

Explanation: The velocity and area are multiplied by the conversion factor to get the flow rate in GPM.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate measurement ensures proper system operation, helps in equipment selection, and maintains process efficiency.

4. Using the Calculator

Tips: Enter the fluid velocity in ft/s and the pipe's cross-sectional area in ft². All values must be > 0.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I measure velocity?
A: Use a flow meter or calculate from flow rate and pipe dimensions (V = Q/(A × 448.83)).

Q3: How do I calculate cross-sectional area?
A: For circular pipes, A = π × (diameter/2)². Convert diameter to feet if necessary.

Q4: What applications use this calculation?
A: Fuel transfer systems, chemical processing, water treatment, and any liquid transfer applications.

Q5: Are there limitations to this formula?
A: This assumes steady, incompressible flow and may need adjustment for viscous fluids or non-standard conditions.
