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 (usually water).

2. How Does the Calculator Work?

The calculator uses the formula:

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

Where:

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

Explanation: This formula calculates the specific gravity of a particle based on its settling velocity in a fluid, accounting for particle diameter and temperature effects.

3. Importance of Specific Gravity Calculation

Details: Calculating specific gravity of particles is crucial in various engineering applications including sedimentation processes, mineral processing, water treatment, and soil mechanics. It helps determine particle behavior in fluid media.

4. Using the Calculator

Tips: Enter specific gravity of fluid, settling velocity in m/s, diameter in meters, and outside temperature in Fahrenheit. All values must be valid (diameter > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why is temperature conversion needed in this formula?
A: The formula requires temperature in Kelvin for accurate calculations, so Fahrenheit inputs are converted to maintain dimensional consistency.

Q2: What is the significance of the constant 418 in the formula?
A: This is an empirical constant that accounts for gravitational acceleration and fluid properties in the settling velocity relationship.

Q3: How does particle diameter affect the specific gravity calculation?
A: Larger diameters result in lower specific gravity values for the same settling velocity, as larger particles settle faster due to increased mass.

Q4: What are typical ranges for specific gravity of particles?
A: Most mineral particles range from 2.5 to 5.0, while organic particles typically range from 1.0 to 1.5.

Q5: Can this formula be used for all types of particles?
A: This formula works best for spherical particles in laminar flow conditions. Irregular shapes or turbulent conditions may require additional corrections.
