Fluid Mechanics Buoyancy Calculator: Specific Gravity & Water Weight Loss

Calculate Specific Gravity and Water Weight Loss

N

Explore fluid mechanics buoyancy with our specific gravity and water weight loss calculator. Quickly determine an object's specific gravity and the buoyant force (weight loss in water) using its weight in air and submerged weight. Ideal for students and engineers studying Archimedes' Principle and object flotation.

Formula:

Water Weight Loss (Buoyant Force):

Fb = Wair - Wwater

Where:

  • Fb = Buoyant Force / Water Weight Loss
  • Wair = Weight of object in air
  • Wwater = Weight of object submerged in water

Specific Gravity:

SG = Wair / (Wair - Wwater)

Where:

  • SG = Specific Gravity (dimensionless)
  • Wair = Weight of object in air
  • Wwater = Weight of object submerged in water
