1. What is the Fluid Flow Rate Equation?

The fluid flow rate equation (Q = A × v) calculates the volumetric flow rate of a fluid through a given cross-sectional area. It's a fundamental equation in fluid dynamics and engineering applications.

2. How Does the Calculator Work?

The calculator uses the fluid flow rate equation:

Where:

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

Explanation: The equation calculates how much volume of fluid passes through a given cross-section per unit time, based on the area and flow velocity.

3. Importance of Flow Rate Calculation

Details: Flow rate calculation is essential for designing piping systems, hydraulic engineering, water supply systems, and various industrial processes involving fluid transport.

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 greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use for the inputs?
A: Use square meters (m²) for area and meters per second (m/s) for velocity to get flow rate in cubic meters per second (m³/s).

Q2: Can I use different units?
A: Yes, but you'll need to convert the result accordingly. The calculator uses standard SI units.

Q3: Does this equation work for all fluids?
A: Yes, the basic 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 flows, you would need to integrate the velocity profile across the cross-sectional area.

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