Re = ρ*uf*d/η
This formula uses 4 Variables
Variables Used
Density - The 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. (Measured in Kilogram per Meter³)
Fluid Velocity - Fluid velocity is the volume of fluid flowing in the given vessel per unit cross sectional area. (Measured in Meter per Second)
Diameter - Diameter is a straight line passing from side to side through the center of a body or figure, especially a circle or sphere. (Measured in Meter)
Dynamic viscosity - Dynamic viscosity is the measurement of the fluid's internal resistance to flow while kinematic viscosity refers to the ratio of dynamic viscosity to density. (Measured in Poise)
