1. What is Immersed Weight?

Immersed weight refers to the apparent weight of an object when submerged in a fluid. It's the actual weight minus the buoyant force acting on the object according to Archimedes' principle.

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 accounts for the buoyant force which reduces the apparent weight of an object when submerged in a fluid.

3. Importance of Immersed Weight Calculation

Details: Calculating immersed weight is crucial for designing ships, submarines, and other floating structures. It's also important in hydrostatic weighing for body composition analysis.

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's the difference between weight and immersed weight?
A: Weight is the force due to gravity acting on an object's mass. Immersed weight is reduced by the buoyant force when the object is submerged in a fluid.

Q2: What happens if immersed weight is negative?
A: A negative immersed weight means the object will float, as the buoyant force exceeds the object's weight.

Q3: How does fluid density affect immersed weight?
A: Higher fluid density increases buoyant force, resulting in lower immersed weight for the same object.

Q4: What are typical applications of this calculation?
A: Ship design, underwater weighing, determining specific gravity of objects, and analyzing floating structures.

Q5: Why is volume important in this calculation?
A: The buoyant force equals the weight of the displaced fluid, which depends on both fluid density and the volume displaced.
