1. What is the Flow Rate Formula?

The flow rate formula (Q = A × v) calculates the volumetric flow rate of a fluid through a cross-sectional area. It's a fundamental equation in fluid dynamics used to determine how much fluid passes through a given point per unit time.

2. How Does the Calculator Work?

The calculator uses the flow rate equation:

Where:

• \( Q \) — Flow rate (m³/s)
• \( A \) — Cross-sectional area (m²)
• \( v \) — Velocity (m/s)

Explanation: The equation multiplies the cross-sectional area through which the fluid flows by the average velocity of the fluid to determine the volumetric flow rate.

3. Importance of Flow Rate Calculation

Details: Flow rate calculation is essential in various engineering applications including pipe sizing, pump selection, irrigation systems, and HVAC design. It helps ensure proper fluid transport and system efficiency.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the calculation?
A: For consistent results, use meters for area (m²) and meters per second for velocity (m/s), which will give flow rate in cubic meters per second (m³/s).

Q2: Can I use different units?
A: Yes, but you'll need to ensure unit consistency. For example, using cm² for area and cm/s for velocity will give flow rate in cm³/s.

Q3: Does this formula work for all fluids?
A: Yes, the formula Q = A × v works for both liquids and gases, assuming the velocity is uniform across the cross-section.

Q4: What if the velocity isn't uniform?
A: For non-uniform velocity profiles, you would need to integrate the velocity across the area or use an average velocity value.

Q5: How accurate is this calculation?
A: The calculation is mathematically precise, but its accuracy in real-world applications depends on the accuracy of your area and velocity measurements.
