Terminal velocity relation with radius
WebHere, it should be noted that the terminal speed of the sphere is directly proportional to the square of its radius. If σ is greater than ρ, then the term (ρ - σ) becomes negative leading … WebThe maximum velocity of a body travelling through a viscous fluid is called terminal velocity. It is achieved when the medium's force of resistance equals and opposes the force of …

WebTerminal Velocity calculator uses Terminal Velocity = (2/9)*Radius^2* (Density of the first phase-Density of the second phase)*Acceleration Due To Gravity/Dynamic Viscosity to calculate the Terminal Velocity, Terminal velocity is the maximum velocity attainable by an object as it falls through a fluid (air is the most common example). WebAnother important relationship is that velocity, at constant flow, is inversely related to the radius squared (V ∝ 1 / r 2 at constant flow). In the example shown in the figure, reducing the radius by 50% causes the velocity to increase 4 fold at constant flow. This relationship has important implications for turbulent flow and the Bernoulli ...
