Velocity Of Flow Formula:
| From: | To: |
The Velocity of Fluid refers to the rate at which a fluid particle moves in a specific direction. It is a vector quantity, meaning it has both magnitude and direction. Velocity Head represents the kinetic energy of a fluid flow per unit weight.
The calculator uses the formula:
Where:
Explanation: This formula calculates the velocity of fluid flow based on the velocity head concept, which represents the kinetic energy component in Bernoulli's equation for steady non-viscous flow.
Details: Accurate velocity calculation is crucial for fluid dynamics analysis, pipe sizing, pump selection, and understanding energy distribution in fluid systems. It helps engineers design efficient fluid transport systems.
Tips: Enter velocity head in meters. The value must be positive and greater than zero. The calculator will compute the corresponding fluid velocity.
Q1: What is velocity head?
A: Velocity head represents the kinetic energy of a fluid per unit weight and is expressed in length units (meters). It's calculated as V²/2g where V is velocity and g is gravitational acceleration.
Q2: When is this formula applicable?
A: This formula applies to steady, non-viscous, incompressible flow where energy losses due to friction are negligible.
Q3: What are typical velocity values in pipe flow?
A: Typical velocities range from 1-3 m/s for water in pipes, but can vary significantly depending on the application and fluid properties.
Q4: How does viscosity affect this calculation?
A: For viscous fluids, additional factors like Reynolds number and friction losses need to be considered, making this simplified formula less accurate.
Q5: Can this be used for compressible fluids?
A: No, this formula assumes incompressible flow. For compressible fluids like gases, different equations accounting for density changes are required.
