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 is 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:

Where:

• Specific Gravity of Particle - Ratio of particle density to reference density
• Settling Velocity - Terminal velocity of particle in fluid (m/s)
• Diameter - Particle diameter (m)
• Temperature - Outside temperature converted to Kelvin

3. Importance of Specific Gravity Calculation

Details: Calculating specific gravity of fluid is crucial in various engineering applications including sedimentation analysis, particle separation processes, and fluid mechanics calculations where buoyancy effects are significant.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Why is temperature conversion necessary?
A: The formula requires temperature in Kelvin for accurate calculations, while input is accepted in Fahrenheit for user convenience.

Q2: What are typical values for specific gravity?
A: Water has specific gravity of 1.0. Most fluids range from 0.8 to 1.5, with heavier fluids having higher values.

Q3: When is this calculation particularly useful?
A: This calculation is essential in sedimentation studies, wastewater treatment, mineral processing, and any application involving particle settling in fluids.

Q4: Are there limitations to this formula?
A: The formula assumes spherical particles and may have reduced accuracy for non-spherical particles or in non-Newtonian fluids.

Q5: How does temperature affect the calculation?
A: Temperature affects fluid viscosity and density, which influences settling velocity and ultimately the specific gravity calculation.
