Density

Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.

Symbol: ρ

Measurement: DensityUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Density

Fluid Velocity

Fluid velocity is the volume of fluid flowing in the given vessel per unit cross sectional area.

Symbol: u_Fluid

Measurement: SpeedUnit: m/s

Note: Value can be positive or negative.

Formulas to find Fluid Velocity

Characteristic Length

A characteristic length is usually the volume of a system divided by its surface.

Symbol: L_c

Measurement: LengthUnit: m

Note: Value should be greater than 0.
