Fluid Velocity Equation:
| From: | To: |
Fluid velocity is the speed at which a fluid flows through a given cross-sectional area. It's a fundamental concept in fluid dynamics that describes how fast fluid particles are moving through a pipe, channel, or other conduit.
The calculator uses the fluid velocity equation:
Where:
Explanation: The equation calculates how fast a fluid is moving by dividing the volume of fluid passing through per second by the cross-sectional area of the flow path.
Details: Calculating fluid velocity is essential for designing piping systems, determining flow characteristics, calculating pressure drops, and ensuring efficient fluid transport in various engineering applications.
Tips: Enter flow rate in cubic meters per second (m³/s) and cross-sectional area in square meters (m²). Both values must be positive numbers greater than zero.
Q1: What units should I use for flow rate and area?
A: The calculator uses SI units: flow rate in m³/s and area in m². Make sure to convert your measurements to these units before calculation.
Q2: Can this calculator be used for any type of fluid?
A: Yes, the velocity calculation applies to all Newtonian fluids (water, air, oil, etc.) as it's based on volumetric flow principles.
Q3: What is a typical velocity range for water in pipes?
A: Typical water velocities in pipes range from 0.5-3 m/s, with higher velocities potentially causing erosion and lower velocities risking sedimentation.
Q4: How does pipe diameter affect fluid velocity?
A: For a constant flow rate, velocity increases as pipe diameter decreases, following an inverse square relationship (velocity ∝ 1/diameter²).
Q5: Can I use this for compressible fluids like gases?
A: This calculator assumes incompressible flow. For compressible fluids like gases at high velocities, additional factors like density changes must be considered.
