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 a dimensionless quantity that indicates how dense a particle is compared to a reference substance.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ G = G_f + \frac{V_s \times 100}{418 \times D_{particle} \times (3 \times T_F + 70)} \]

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 its settling velocity, diameter, the surrounding fluid's specific gravity, and temperature conditions.

3. Importance of Specific Gravity Calculation

Details: Calculating specific gravity of particles is crucial in various engineering and scientific applications, including sedimentation studies, particle separation processes, fluid mechanics, and environmental engineering where particle behavior in fluids needs to be analyzed.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the reference standard for specific gravity?
A: For liquids and solids, the reference is usually pure water at 4°C (density = 1 g/cm³). For gases, the reference is typically air.

Q2: Why is temperature considered in this calculation?
A: Temperature affects fluid density and viscosity, which in turn influence the settling velocity of particles in the fluid.

Q3: What applications use this specific gravity calculation?
A: This calculation is used in wastewater treatment, mining operations, soil mechanics, and any process involving particle sedimentation or flotation.

Q4: How does particle diameter affect the calculation?
A: Larger particles generally have higher settling velocities, while smaller particles settle more slowly due to greater surface area to mass ratio.

Q5: Can this formula be used for all particle sizes?
A: This specific formula is designed for particles with diameter greater than 0.1mm. Different equations may be needed for smaller particles.
