The weight or the gravity force acting on the brick - common red brick has specific gravity 1. The buoyant force acting on the brick is equal to the weight of the water displaced by the brick and can be calculated asį B = (( 65.25 in 3 ) / (1728 in/ft 3 )) ( 1.940 slugs/ft 3 ) ( 32.174 ft/s 2 ) The volume of the brick can be calculated = 950 kg/m 3 Example - Buoyant force acting on a Brick submerged in WaterĪ standard brick with actual size 3 5/8 x 2 1/4 x 8 (inches) is submerged in water with density 1.940 slugs /ft 3. Chapter 2 (Section 2.2.5) outlines an analysis of slug stability which points out the importance of understanding the rate at which slugs shed liquid. įor a floating body the buoyant force is equal to the weight of the water displaced by the body.Īnd the density of the body can be calculated as It explains the initiation of slugs for very viscous liquids, for high-density gases, for gas velocities where wave coalescence is important and for the evolution of pseudo-slugs into slugs. G = acceleration of gravity (9.81 m/s 2, 32.174 ft/s 2 )Įxample - Density of a Body that floats in WaterĪ floating body is 95% submerged in water with density 1000 kg/m 3. The exact value is actually slightly lower. The density of water is about 1 gram per milliliter (g/ml), 1 gram per cubic centimeter (g/cm 3 ), 1000 kg/m 3, or 62 pounds per cubic foot (lb/ft 3 ). For all practical purposes, this is the same as the weight of water per unit of volume. Ρ = density of fluid (kg/m 3, slugs/ft 3 ) The density of water is the mass of water per unit of volume. Γ = ρ g = specific weight of fluid (weight per unit volume) (N/m 3, lb f /ft 3 ) V = volume of body below surface of liquid (m 3, ft 3 )

W = weight (gravity force) of displaced liquid (N, lb f ) 'If a solid body floats or is submerged in a liquid - the liquid exerts an upward thrust force - a buoyant force - on the body equal to the gravitational force on the liquid displaced by the body.'į B = buoyant force acting on submerged or floating body (N, lb f )
