Unravel the mysteries of how objects float or sink! Our Fluid Mechanics Buoyancy Calculator helps you determine buoyant force, specific gravity, and the weight of displaced water for objects submerged in various fluids. Perfect for understanding Archimedes' Principle in physics and engineering applications.
Formula:
To calculate buoyancy force, specific gravity, and the weight of displaced fluid, use the following formulas:
- Variables:
- Wair: Weight of the object in air (Newtons)
- Wfluid: Weight of the object when fully submerged in the fluid (Newtons)
- ρfluid: Density of the fluid (kg/m³)
- ρwater: Density of reference water (1000 kg/m³)
- g: Acceleration due to gravity (9.80665 m/s²)
- Formulas:
- Buoyancy Force (Fb) = Wair - Wfluid
- Volume of Displaced Fluid (Vdisplaced) = Fb / (ρfluid × g)
- Density of Object (ρobject) = (Wair × ρfluid) / Fb
- Specific Gravity (SG) = ρobject / ρwater
- Equivalent Weight of Water Displaced (Wwater_displaced) = Vdisplaced × ρwater × g
