This formula uses 6 Variables

Variables Used

Pressure Gradient - (Measured in Newton per Cubic Meter) - Pressure Gradient is the change in pressure with respect to radial distance of element.
Dynamic Viscosity - (Measured in Pascal Second) - Dynamic Viscosity of a fluid is the measure of its resistance to flow when an external force is applied.
Porosity - Porosity is the ratio of volume of voids to volume of soil.
Velocity - (Measured in Meter per Second) - Velocity is a vector quantity (it has both magnitude and direction) and is the rate of change of the position of an object with respect to time.
Sphericity of Particle - Sphericity of Particle is a measure of how closely the shape of an object resembles that of a perfect sphere.
Equivalent Diameter - (Measured in Meter) - Equivalent diameter is the diameter equivalent to the given value.

STEP 1: Convert Input(s) to Base Unit

Dynamic Viscosity: 0.59 Poise --> 0.059 Pascal Second (Check conversion here)
Porosity: 0.5 --> No Conversion Required
Velocity: 60 Meter per Second --> 60 Meter per Second No Conversion Required
Sphericity of Particle: 18.46 --> No Conversion Required
