1. What is Flow Rate?

Flow rate is the volume of fluid that passes through a given surface per unit time. It's a fundamental concept in fluid dynamics and is used in various engineering and scientific applications.

2. How Does the Calculator Work?

The calculator uses the basic flow rate equation:

Where:

• Velocity — Speed of the fluid (m/s)
• Area — Cross-sectional area of flow (m²)

Explanation: The equation calculates the volumetric flow rate by multiplying the fluid velocity by the cross-sectional area through which the fluid is flowing.

3. Importance of Flow Rate Calculation

Details: Flow rate calculations are essential in designing piping systems, ventilation systems, hydraulic systems, and in various industrial processes involving fluid transport.

4. Using the Calculator

Tips: Enter velocity in meters per second (m/s) and area in square meters (m²). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses SI units - meters per second (m/s) for velocity and square meters (m²) for area, resulting in cubic meters per second (m³/s) for flow rate.

Q2: Can I use different units?
A: You'll need to convert your units to SI units before entering them, or modify the calculation to handle unit conversions.

Q3: Does this work for all fluid types?
A: The basic equation works for all incompressible fluids. For compressible fluids, additional factors like density changes must be considered.

Q4: What if my flow isn't uniform?
A: For non-uniform flows, you may need to integrate velocity across the area or use average velocity values.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the given inputs, but real-world accuracy depends on how well your measurements represent the actual flow conditions.
