1. Cauchy Number (Ca)

To calculate the Cauchy Number, you need the following:

Where:

  • = Density of the fluid (kg/m³)
  • = Flow velocity (m/s)
  • = Characteristic length (m)
  • = Surface tension of the fluid (N/m)

What you need to provide:

  • Density
  • Flow velocity
  • Characteristic length
  • Surface tension

2. Bulk Modulus of Elasticity (K)

The formula for Bulk Modulus is:

Where:

  • = Initial volume (m³)
  • = Change in pressure (Pa)
  • = Change in volume (m³)

What you need to provide:

  • Initial volume
  • Change in pressure
  • Change in volume

3. Density (ρ)

Density can be calculated using:

Where:

  • = Mass (kg)
  • = Volume (m³)

What you need to provide:

  • Mass
  • Volume

4. Flow Velocity (u)

Flow velocity is calculated using:

Where:

  • = Flow rate (m³/s)
  • = Cross-sectional area (m²)

What you need to provide:

  • Flow rate
  • Cross-sectional area
