Buoyant Force Formula:
From: | To: |
Definition: The 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.
Purpose: This principle explains why objects float or sink and is fundamental in fluid mechanics and naval architecture.
The calculator uses the formula:
Where:
Explanation: The force equals the product of water density, displaced volume, and gravitational acceleration.
Details: Understanding buoyancy is crucial for designing ships, submarines, flotation devices, and understanding natural phenomena.
Tips: Enter water density (default 1000 kg/m³), displaced volume in cubic meters, and gravitational acceleration (default 9.81 m/s²). All values must be > 0.
Q1: Does this work for other fluids besides water?
A: Yes, simply change the density value to match your fluid (e.g., 1027 kg/m³ for seawater).
Q2: How do I find the displaced volume?
A: For fully submerged objects, it's equal to the object's volume. For floating objects, it's the volume below the waterline.
Q3: Why is gravity included in the formula?
A: The buoyant force equals the weight of displaced fluid, and weight depends on gravity.
Q4: What if my object is only partially submerged?
A: Use only the submerged volume in your calculation.
Q5: How does this relate to Archimedes' Principle?
A: This formula is the mathematical expression of Archimedes' Principle.
