In a falling-ball viscometer, a steel sphere with a diameter of 1.200 in drops through a heavy syrup and travels 18.0 in. in 20.40 s at a constant speed. Compute the viscosity of the syrup. The syrup has a specific gravity of 1.18. Note that the free-body diagram of the sphere should include its weight acting down and the buoyant force and the drag force acting up. The steel has a specific gravity of7.83. See also Chapter 2.
