1. What is Effective Weight of Particle?

Effective Weight of Particle is the difference between the total weight of a particle and the buoyant force acting upon it when submerged in a fluid. It represents the net downward force experienced by the particle in the fluid medium.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Total Weight of Particle — The gravitational force acting on the particle (in Newton)
• Force due to Buoyancy — The upward force exerted by the fluid on the particle (in Newton)

Explanation: This calculation determines the net weight experienced by a particle when submerged in a fluid, accounting for the buoyant force that opposes gravity.

3. Importance of Effective Weight Calculation

Details: Calculating effective weight is crucial in fluid mechanics, sedimentation processes, particle separation techniques, and understanding the behavior of objects in fluids. It helps determine whether a particle will sink, float, or remain suspended in a fluid.

4. Using the Calculator

Tips: Enter the total weight of the particle and the buoyancy force in Newtons. Both values must be positive numbers. The calculator will compute the effective weight in Kilograms.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between effective weight and buoyancy?
A: Effective weight decreases as buoyancy increases. When buoyancy equals total weight, the effective weight becomes zero and the particle becomes neutrally buoyant.

Q2: How does effective weight affect particle settling?
A: Particles with higher effective weight settle faster in fluids, while those with lower effective weight settle slower or may remain suspended.

Q3: Can effective weight be negative?
A: Yes, if the buoyant force exceeds the total weight of the particle, the effective weight becomes negative, causing the particle to float upward.

Q4: What factors affect buoyancy force?
A: Buoyancy force depends on the density of the fluid, the volume of the displaced fluid, and gravitational acceleration.

Q5: How is this calculation used in real-world applications?
A: This calculation is essential in water treatment plants, mining operations, chemical processing, and any industry where particle separation in fluids is required.
