This calculator determines the Terminal Settling Velocity, which is crucial in fluid mechanics for predicting the settling behavior of spherical particles in a fluid.
It is widely used in sedimentation analysis, wastewater treatment, and industrial separation processes to ensure efficiency and accuracy.
Settling-VelocitySettling velocity is the speed at which a particle falls through a fluid due to gravity, influenced by particle size, density, fluid viscosity, and flow conditions
Explanation of Parameters:
Density of Particle (ρₚ): The mass per unit volume of the settling particle, measured in kg/m³.
Density of Fluid (ρ_f): The mass per unit volume of the fluid medium, measured in kg/m³.
Diameter of Sphere (d): The size of the particle, measured in meters.
Viscosity of Fluid (μ): The fluid's resistance to deformation, measured in Pa·s.
Terminal Settling Velocity (vₜ): The constant velocity at which a particle settles in a fluid due to gravity.
Reynolds Number (Re): A dimensionless value that determines the flow regime around the particle.
Drag Coefficient (C_D): A factor that accounts for resistance experienced by the particle while settling.
