1. What is Immersed Weight?

The immersed weight is 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 formula:

Where:

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

Explanation: The buoyant force equals the weight of the displaced fluid (Archimedes' principle), which is subtracted from the object's actual weight.

3. Importance of Immersed Weight Calculation

Details: Calculating immersed weight is crucial for designing floating structures, determining buoyancy, and understanding fluid mechanics principles.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: What is the difference between mass and weight in this context?
A: Mass is a measure of matter (kg), while weight is the force due to gravity (N). This calculator uses weight (force).

Q2: Does this work for any liquid?
A: Yes, as long as you know the liquid's density. Common values: water = 1000 kg/m³, seawater ≈ 1025 kg/m³.

Q3: What if the object floats?
A: For floating objects, the immersed weight would be zero (buoyant force equals the object's weight).

Q4: How does temperature affect the calculation?
A: Temperature affects liquid density. Use the correct density for the liquid at its current temperature.

Q5: Can this be used for gases?
A: The principle applies, but gas densities are much lower, making the effect usually negligible.
