1. What is the Flow Rate Formula?

Definition: The flow rate formula calculates the volumetric flow rate of a fluid through a given cross-sectional area.

Purpose: It helps engineers, plumbers, and scientists determine how much fluid passes through a pipe or channel per unit time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

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

Explanation: The flow rate is simply the product of the cross-sectional area and the average velocity of the fluid.

3. Importance of Flow Rate Calculation

Details: Proper flow rate estimation is essential for designing piping systems, irrigation channels, and hydraulic systems.

4. Using the Calculator

Tips: Enter the cross-sectional area in square meters and flow velocity in meters per second. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units should I use?
A: The calculator uses metric units (m² for area, m/s for velocity, m³/s for flow rate). Convert other units before input.

Q2: Does this work for any fluid?
A: Yes, the formula applies to all incompressible fluids (water, oil, etc.) flowing through a defined area.

Q3: How do I measure flow velocity?
A: Use flow meters, or calculate from pressure difference and pipe characteristics.

Q4: What if my pipe isn't circular?
A: Calculate the cross-sectional area based on the actual shape (rectangle, ellipse, etc.).

Q5: Does this account for turbulence?
A: No, this uses average velocity. For precise calculations, consider Reynolds number and flow conditions.
