1. What is Specific Gravity of Particle?

Specific Gravity of Particle is the ratio of density of particle to density of standard material. It's an important parameter in fluid mechanics and sedimentation processes.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( G \) — Specific Gravity of Particle
• \( G_f \) — Specific Gravity of Fluid
• \( V_s \) — Settling Velocity (m/s)
• \( D_{particle} \) — Diameter of Particle (mm)
• \( T_F \) — Temperature in Fahrenheit (°F)

Explanation: This formula calculates the specific gravity of a particle based on fluid properties, settling velocity, particle diameter, and temperature in Fahrenheit.

3. Importance of Specific Gravity Calculation

Details: Calculating specific gravity of particles is crucial for understanding sedimentation rates, designing separation processes, and analyzing particle behavior in fluids.

4. Using the Calculator

Tips: Enter specific gravity of fluid, settling velocity in m/s, particle diameter in mm (must be ≥0.1mm), and temperature in Fahrenheit. All values must be valid.

5. Frequently Asked Questions (FAQ)

Q1: Why is particle diameter limited to ≥0.1mm?
A: This formula is specifically designed for particles with diameter greater than 0.1mm as the relationship changes for smaller particles.

Q2: What is the standard material for specific gravity comparison?
A: Typically water at 4°C is used as the standard material with specific gravity of 1.0.

Q3: How does temperature affect the calculation?
A: Temperature affects fluid density and viscosity, which influences settling velocity and therefore the specific gravity calculation.

Q4: What are typical settling velocity values?
A: Settling velocity varies greatly depending on particle size and density, ranging from millimeters to centimeters per second.

Q5: Can this formula be used for all particle types?
A: This formula works best for spherical particles in Newtonian fluids. Irregular shapes may require additional correction factors.
