1. What is a Flow Rate Calculator?

Definition: This calculator computes the volumetric flow rate (Q) based on the cross-sectional area (A) and flow velocity (V) using the fundamental flow rate equation.

Purpose: It helps engineers, plumbers, and fluid dynamics professionals determine how much fluid passes through a given area per unit time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Q \) — Volumetric flow rate (cubic meters per second)
• \( A \) — Cross-sectional area (square meters)
• \( V \) — Flow velocity (meters per second)

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

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculations are essential for designing piping systems, irrigation channels, HVAC systems, and any application involving fluid transport.

4. Using the Calculator

Tips: Enter the cross-sectional area in m² and flow velocity in m/s. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What units does this calculator use?
A: The calculator uses metric units (m² for area, m/s for velocity, m³/s for flow rate).

Q2: Can I use different units?
A: You must convert your measurements to metric units before inputting them into the calculator.

Q3: Does this work for all fluid types?
A: Yes, the basic formula applies to all Newtonian fluids (water, air, oil, etc.) under laminar flow conditions.

Q4: What if my flow is turbulent?
A: The basic formula still applies, but you may need to consider additional factors like friction losses in practical applications.

Q5: How do I measure flow velocity?
A: Velocity can be measured with flow meters or calculated from pressure differentials or other flow characteristics.
