1. What is a Liquid Flow Rate Calculator?

Definition: This calculator determines the volumetric flow rate of a liquid through a pipe or channel based on cross-sectional area and flow velocity.

Purpose: It helps engineers, plumbers, and fluid system designers calculate how much liquid is moving through a system 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 area through which the liquid flows and the speed at which it's moving.

3. Importance of Flow Rate Calculation

Details: Accurate flow rate calculations are essential for designing piping systems, irrigation systems, and industrial fluid processes.

4. Using the Calculator

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

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, and m³/s for flow rate).

Q2: Can I use this for gases?
A: While the basic principle is the same, gas flow calculations often require additional factors like compressibility.

Q3: How do I measure flow velocity?
A: Velocity can be measured with flow meters or calculated from pressure differentials in pipe systems.

Q4: What's a typical flow velocity in pipes?
A: For water, typical velocities range from 0.5-3 m/s depending on application and pipe size.

Q5: How does pipe diameter affect the calculation?
A: Diameter determines the cross-sectional area (A = πr² for circular pipes).
