Calculation Formula

Face Velocity (V) = Flow Rate (Q) / Cross-sectional Area (A)

Where:
V = Face Velocity (m/s)
Q = Flow Rate (m³/s)
A = Cross-sectional Area (m²)

What is Face Velocity?

Face velocity is the average velocity of a fluid (liquid or gas) across an open area or orifice. It's an important parameter in fluid dynamics, particularly in hydraulic and pneumatic systems.

How to Use This Calculator

  1. Enter the flow rate (Q) in cubic meters per second (m³/s)
  2. Enter the cross-sectional area (A) in square meters (m²)
  3. Click the "Calculate" button to compute the face velocity
  4. The result will be displayed in meters per second (m/s)

Principle and Formula

The face velocity is calculated using the fundamental fluid dynamics equation:

V = Q/A

Where:

  • V = Face Velocity (m/s)
  • Q = Flow Rate (m³/s)
  • A = Cross-sectional Area (m²)

Applications

This calculator is useful in various engineering applications including:

  • Water treatment plants
  • HVAC systems
  • Air pollution control
  • Industrial fluid processing

Example

If a pipe with a flow rate of 0.5 m³/s has a cross-sectional area of 0.2 m², the face velocity would be:

V = 0.5 / 0.2 = 2.5 m/s
