For an air bubble terminal velocity is
WebSince the density of air is less than that of oil, the air bubble will rise up through the liquid. Hence, the viscous force is downward. At terminal velocity, this downward viscous force is equal in magnitude to the net upward force. Viscous force = buoyant force - the gravitational force ∴ 6 π η r v t = 3 4 π r 3 (ρ L − ρ a i r) g ∴ ... Websingle air bubble in seawater, the drug coefficient is also investigated. Furthermore, the measured terminal velocity of a crowd of air bubbles rising in seawater, is shown for …
