1. What is the Air Weight Formula?

The Air Weight formula calculates the total weight of an object when partially or fully immersed in a fluid, taking into account the buoyant force and the object's actual weight.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \text{Air Weight} = (\text{Immersed Depth} \times \text{Fluid Specific Weight} \times \text{Cross Section Area Level}) + \text{Body Weight} \] \[ W_a = (D_{im} \times \gamma \times A) + W_b \]

Where:

\( D_{im} \) — Immersed Depth (m)
\( \gamma \) — Fluid Specific Weight (N/m³)
\( A \) — Cross Section Area Level (m²)
\( W_b \) — Body Weight (kg)

Explanation: The formula accounts for the buoyant force exerted by the fluid on the immersed object, which affects its apparent weight.

3. Importance of Air Weight Calculation

Details: Accurate air weight calculation is crucial for various engineering applications, including buoyancy analysis, fluid mechanics, and structural design involving submerged objects.

4. Using the Calculator

Tips: Enter immersed depth in meters, fluid specific weight in N/m³, cross section area in m², and body weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is fluid specific weight?
A: Fluid specific weight is the weight per unit volume of a fluid, typically measured in N/m³ or lb/ft³.

Q2: How does immersed depth affect air weight?
A: As immersed depth increases, the buoyant force increases, which affects the apparent weight of the object in the fluid.

Q3: What is cross section area level?
A: It is the surface area of the object that is perpendicular to the direction of immersion and in contact with the fluid.

Q4: Can this formula be used for gases?
A: Yes, the formula applies to both liquids and gases, though the fluid specific weight values will differ significantly.

Q5: What are typical applications of this calculation?
A: This calculation is used in submarine design, shipbuilding, underwater construction, and various hydraulic engineering applications.
