    Terminal Velocity Steel Ball Bearing in Oil

    Force of drag = 1/2 * (density of fluid) * (area of sphere) * v^2 * (coefficient of drag) Force of drag = 3 * pi * (coefficient of fluid) * (diameter of obj) * v Coefficient of drag = 24 / (Reynolds number) Reynolds number = (density of fluid * velocity of fluid * chracteristic...

    Calculating Terminal Velocity in a Fluid

    Homework Statement A 1.5-mm-diameter steel ball bearing (7830 kg/m^3) is dropped into a tank of SAE 30 oil. What is its terminal velocity? The density of oil is 917kg/m^3, and the viscosity of oil is 0.26kg/(m*s). Help is much appreciated! Homework Equations Force of drag = 1/2 *...
