Objects falling through a fluid will attain a "terminal velocity" determined by gravity force, buoyant force and kinetic force. Our experiment was designed to investigate the effect of those various factors on the terminal velocity. In this experiment, fluids with high viscosity such as silicone oil and glycerine are used to slow down the terminal velocities. For the sake of the simple calculations, spherical balls were chosen. If the densities of balls and fluids, and the viscosity of fluids are known as well as measured are the radii and terminal velocities of the balls, we can calculate the drag coefficient(CD) and Reynolds Number (Re). |
