1. What is the Flow Rate Equation?

The flow rate equation (Q = A × v) calculates the volumetric flow rate of a fluid by multiplying the cross-sectional area of flow by the average velocity of the fluid. This fundamental equation is used in fluid dynamics and engineering applications.

2. How Does the Calculator Work?

The calculator uses the flow rate equation:

Where:

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

Explanation: The equation represents the volume of fluid passing through a given cross-section per unit time.

3. Importance of Flow Rate Calculation

Details: Flow rate calculation is essential in designing piping systems, water distribution networks, hydraulic engineering, and many industrial processes involving fluid transport.

4. Using the Calculator

Tips: Enter cross-sectional area in square meters and velocity in meters per second. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: The calculator expects area in square meters (m²) and velocity in meters per second (m/s) for consistent results in m³/s.

Q2: Can I use different units?
A: Yes, but you'll need to convert your units to maintain dimensional consistency in the result.

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

Q4: What if the flow is not uniform?
A: For non-uniform flow, the equation provides an average flow rate. More complex integration may be needed for precise calculations.

Q5: How accurate is this calculation?
A: The calculation is mathematically exact for the given inputs. Accuracy depends on the precision of your measurements for area and velocity.
