1. What is the Immersed Weight Formula?

The immersed weight formula calculates the apparent weight of an object when submerged in a fluid. It accounts for the buoyant force acting on the object, which reduces its apparent weight.

2. How Does the Calculator Work?

The calculator uses the immersed weight equation:

Where:

• \( W \) — Weight in air (N)
• \( \rho_f \) — Fluid density (kg/m³)
• \( V \) — Volume of displaced fluid (m³)
• \( g \) — Acceleration due to gravity (9.81 m/s²)

Explanation: The equation subtracts the buoyant force (ρ_f V g) from the object's actual weight to determine its apparent weight in the fluid.

3. Importance of Immersed Weight Calculation

Details: Calculating immersed weight is essential in fluid mechanics, shipbuilding, underwater construction, and any application where objects are submerged in fluids.

4. Using the Calculator

Tips: Enter weight in newtons, fluid density in kg/m³, and volume in cubic meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is buoyant force?
A: Buoyant force is the upward force exerted by a fluid on an immersed object, equal to the weight of the fluid displaced by the object.

Q2: How does fluid density affect immersed weight?
A: Higher fluid density results in greater buoyant force and thus lower apparent weight when immersed.

Q3: What happens if the immersed weight is negative?
A: A negative immersed weight means the object's buoyant force exceeds its weight, causing it to float.

Q4: Does this formula work for all fluids?
A: Yes, as long as you know the fluid's density. The formula works for liquids and gases.

Q5: How is this different from Archimedes' principle?
A: This is a mathematical expression of Archimedes' principle, specifically calculating the apparent weight reduction.
