1. What is Specific Gravity of Fluid?

Specific Gravity of Fluid is the ratio of the density of a fluid to the density of a reference fluid, typically water at 4°C. It's a dimensionless quantity that indicates whether a fluid will float or sink in another fluid.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ G_f = G - \left( \frac{V_S \times 100}{418 \times D^2 \times (3 \times t + 70)} \right) \]

Where:

\( G_f \) — Specific Gravity of Fluid
\( G \) — Specific Gravity of Particle
\( V_S \) — Settling Velocity (m/s)
\( D \) — Diameter (m)
\( t \) — Temperature (°C)

Explanation: This formula calculates the specific gravity of a fluid based on the settling velocity of particles, their specific gravity, diameter, and the temperature of the fluid.

3. Importance of Specific Gravity Calculation

Details: Calculating specific gravity of fluids is crucial in various engineering applications, including sedimentation processes, fluid mechanics, and material separation techniques. It helps determine the behavior of particles in fluids and is essential in designing separation systems.

4. Using the Calculator

Tips: Enter specific gravity of particle, settling velocity in m/s, diameter in meters, and temperature in Celsius. Ensure all values are positive and diameter is greater than zero for accurate calculations.

5. Frequently Asked Questions (FAQ)

Q1: What is the reference fluid for specific gravity calculations?
A: For liquids, water at 4°C (density = 1000 kg/m³) is typically used as the reference fluid.

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

Q3: What are typical values for specific gravity of fluids?
A: Most fluids have specific gravity values between 0.8 and 1.2, with water having a specific gravity of 1.0 at 4°C.

Q4: How does particle diameter affect the calculation?
A: Larger particles generally settle faster due to greater mass, while smaller particles are more affected by fluid viscosity and take longer to settle.

Q5: What applications use this specific gravity calculation?
A: This calculation is used in water treatment plants, mining operations, chemical processing, and environmental engineering for designing sedimentation tanks and separation systems.
