1. What is a Volume Flow Rate Ratio Calculator?

Definition: This calculator determines the ratio between actual and target volumetric flow rates in fluid systems.

Purpose: It helps engineers and technicians assess system performance by comparing actual flow rates to design specifications.

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)
\( Q_{target} \) — Target or designed flow rate (GPM)

Explanation: The ratio indicates whether the system is operating below (R < 1), at (R = 1), or above (R > 1) the target flow rate.

3. Importance of Flow Rate Ratio

Details: Monitoring this ratio helps identify system inefficiencies, pump performance issues, or potential problems in piping networks.

4. Using the Calculator

Tips: Enter both actual and target flow rates in gallons per minute (GPM). Both values must be greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio of 1 mean?
A: A ratio of 1 indicates the system is operating exactly at the target flow rate.

Q2: What's considered an acceptable ratio range?
A: Typically 0.9-1.1 is acceptable, but this depends on specific system requirements.

Q3: When would the ratio be greater than 1?
A: This occurs when the actual flow exceeds the target, possibly due to oversized pumps or lower system resistance than designed.

Q4: How do I measure actual flow rate?
A: Use flow meters installed in the system or perform flow measurements using appropriate techniques.

Q5: Can I use different units than GPM?
A: Yes, as long as both actual and target flow rates use the same units, the ratio will be correct.
