1. What is Fill-Rite Mechanical Fuel Flow Meter?

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

Purpose: It helps in measuring and calculating fuel flow rates in mechanical fuel transfer systems.

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 (cubic feet per second to GPM)

Explanation: The velocity and cross-sectional area are multiplied and converted to GPM using the standard conversion factor.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate measurement ensures proper fuel transfer, system efficiency, and prevents overfilling or underfilling.

4. Using the Calculator

Tips: Enter the velocity in feet per second and the 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 cubic feet per second to gallons per minute (1 ft³/s = 448.83 GPM).

Q2: How do I measure velocity in a fuel system?
A: Use a flow meter or calculate from pipe size and pump capacity.

Q3: What's a typical cross-sectional area?
A: This depends on your pipe diameter (A = π × r²).

Q4: Why use mechanical flow meters?
A: They provide reliable measurements without electrical components in hazardous areas.

Q5: How accurate is this calculation?
A: It provides theoretical flow; actual flow may vary due to friction, viscosity, and other factors.
