1. What is Settling Velocity?

Settling velocity refers to the terminal velocity of a particle in still fluid. It is the constant speed that a particle reaches when the resistance of the fluid equals the gravitational force acting on the particle.

2. How Does the Calculator Work?

The calculator uses the Settling Velocity formula:

\[ V_s = 418 \times (G - G_f) \times D_E^2 \times \left( \frac{t_o + 10}{60} \right) \]

Where:

\( V_s \) — Settling Velocity (m/s)
\( G \) — Specific Gravity of Particle
\( G_f \) — Specific Gravity of Fluid
\( D_E \) — Effective Particle Diameter (m)
\( t_o \) — Outside Temperature (°F)

Explanation: The formula calculates the terminal velocity of particles based on their specific gravity difference with the fluid, particle size, and temperature correction factor.

3. Importance of Settling Velocity Calculation

Details: Settling velocity calculations are crucial in various engineering applications including sedimentation processes, water treatment, mineral processing, and environmental studies where particle separation is required.

4. Using the Calculator

Tips: Enter specific gravity values (dimensionless), effective particle diameter in meters, and outside temperature in Fahrenheit. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is temperature included in the formula?
A: Temperature affects fluid viscosity and density, which influence the settling behavior of particles in the fluid.

Q2: What is the significance of specific gravity difference?
A: The difference between particle and fluid specific gravity determines the buoyant force acting on the particle, which affects its settling rate.

Q3: How does particle size affect settling velocity?
A: Larger particles settle faster due to their greater mass relative to surface area, following the squared relationship in the formula.

Q4: What are typical applications of this calculation?
A: This calculation is used in designing sedimentation tanks, clarifiers, cyclones, and other separation equipment in various industries.

Q5: Are there limitations to this formula?
A: This formula provides an approximation and may need adjustment for non-spherical particles, high concentrations, or non-Newtonian fluids.
