1. What is Immersed Weight?

Immersed weight refers to the apparent weight of an object when submerged in water. It accounts for the buoyant force acting on the object, which reduces its apparent weight compared to its weight in air.

2. How Does the Calculator Work?

The calculator uses the immersed weight formula:

Where:

• \( W \) — Weight in air (N)
• \( V \) — Volume of the object (m³)
• \( g \) — Acceleration due to gravity (m/s²)
• 1000 — Density of water (kg/m³)

Explanation: The formula subtracts the buoyant force (equal to the weight of displaced water) from the object's actual weight to determine its apparent weight in water.

3. Importance of Immersed Weight Calculation

Details: Calculating immersed weight is crucial for designing underwater structures, understanding buoyancy, and solving problems in fluid mechanics. It's used in marine engineering, scuba diving equipment design, and various scientific applications.

4. Using the Calculator

Tips: Enter the object's weight in newtons, its volume in cubic meters, and the gravitational acceleration (default is 9.81 m/s²). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is the density of water 1000 kg/m³ in the formula?
A: This is the standard density of pure water at 4°C. For saltwater, use a higher density (typically 1025 kg/m³).

Q2: What if my object isn't fully submerged?
A: The formula only works for fully submerged objects. For partially submerged objects, you would use the volume of the submerged portion.

Q3: How do I measure the volume of irregular objects?
A: Use water displacement method - measure the volume of water displaced when the object is fully submerged.

Q4: Does this account for the weight of the water itself?
A: No, this calculates the apparent weight of the object in water, not the weight of the water.

Q5: What units should I use for accurate results?
A: The calculator expects weight in newtons (N), volume in cubic meters (m³), and gravity in m/s² for consistent results.
