1. What is a Flow Rate Ratio Calculator?

Definition: This calculator determines the ratio between actual and target flow rates, useful for calibration in systems like 3D printing or fluid pumps.

Purpose: It helps engineers and technicians verify if actual flow rates match desired specifications and make necessary adjustments.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ R = \frac{Q_{actual}}{Q_{target}} \]

Where:

\( R \) — Flow rate ratio (dimensionless)
\( Q_{actual} \) — Actual measured flow rate (GPM or mm³/s)
\( Q_{target} \) — Desired target flow rate (GPM or mm³/s)

Explanation: The ratio indicates how much the actual flow deviates from the target (1.0 = perfect match).

3. Importance of Flow Rate Ratio

Details: Accurate flow rates are critical for process control, quality assurance, and system efficiency in many industrial applications.

4. Using the Calculator

Tips: Enter both actual and target flow rates in consistent units (GPM or mm³/s). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio > 1 mean?
A: The actual flow exceeds the target (over-delivery), which may cause issues like over-extrusion in 3D printing.

Q2: What does a ratio < 1 mean?
A: The actual flow is below target (under-delivery), which may result in insufficient material deposition.

Q3: What's an acceptable ratio range?
A: Typically ±5% (0.95-1.05) is acceptable, but depends on application requirements.

Q4: How do I measure actual flow rate?
A: Use flow meters, timed volume collection, or manufacturer calibration procedures.

Q5: Can I use different units for actual and target?
A: No, both values must be in the same units for a meaningful ratio.
