Erosional Velocity Calculator

Calculators are indispensable tools for various fields, including engineering, physics, and finance. Among these, the erosional velocity calculator holds particular significance in fluid mechanics and petroleum engineering. This tool helps determine the minimum fluid velocity required to prevent sediment deposition in pipelines, a critical factor in maintaining operational efficiency and integrity.

How to Use: Using the erosional velocity calculator is straightforward. Simply input the required parameters, such as fluid density, viscosity, particle density, particle diameter, and pipe diameter, into the designated fields. Once entered, click the “Calculate” button to obtain the erosional velocity.

Formula: The erosional velocity (V<sub>e</sub>) is calculated using the following formula:


  • Ve​ = Erosional velocity (m/s)
  • dp​ = Particle diameter (m)
  • μ = Fluid viscosity (Pa·s)
  • ρf​ = Fluid density (kg/m³)
  • ρp​ = Particle density (kg/m³)
  • g = Acceleration due to gravity (m/s²)
  • D = Pipe diameter (m)

Example Solve: Suppose we have the following values:

  • dp​=0.0005 m
  • μ=0.001 Pa·s
  • ρf​=1000 kg/m³
  • ρp​=2650 kg/m³
  • g=9.81 m/s²
  • D=0.1 m

Using the formula, we can calculate the erosional velocity:
