1. What is a Flow Rate Ratio Calculator?

Definition: This calculator determines the ratio between two flow rates (Q1 and Q2) in cubic meters per second.

Purpose: It helps engineers and fluid system designers compare flow rates and analyze system performance.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( R \) — Flow rate ratio (dimensionless)
• \( Q1 \) — Primary flow rate (m³/s)
• \( Q2 \) — Reference flow rate (m³/s)

Explanation: The ratio is calculated by dividing the primary flow rate (Q1) by the reference flow rate (Q2).

3. Importance of Flow Rate Ratio

Details: Flow rate ratios are critical in hydraulic systems, process control, and when comparing different operating conditions or system designs.

4. Using the Calculator

Tips: Enter both flow rates in cubic meters per second. The calculator will automatically compute their ratio when you click "Calculate".

5. Frequently Asked Questions (FAQ)

Q1: What does the flow rate ratio indicate?
A: It shows how many times larger or smaller Q1 is compared to Q2, helping in system analysis and design.

Q2: Can I use different units for Q1 and Q2?
A: No, both flow rates must be in the same units (m³/s in this calculator) for a meaningful ratio.

Q3: What's a typical application of flow rate ratios?
A: Used in pump sizing, pipe network analysis, and when comparing actual vs. designed flow rates.

Q4: What if Q2 is zero?
A: The calculator requires Q2 > 0 as division by zero is mathematically undefined.

Q5: How precise should my input values be?
A: Use at least 4 decimal places for accurate ratio calculations in most engineering applications.
