An air bubble rises slowly through maple syrup. Three forces act on the bubble, the weight of the bubble, the buoyant force, and a “drag” force due to fluid friction between the bubble and syrup as the bubble forces the syrup out of the way to rise. The drag force is given by F v drag = π6 µ ro where v is the velocity of the bubble and μ is the viscosity of the syrup. Assuming a 5 mm diameter bubble, what is the velocity of the bubble? In which direction does the drag force act? Syrup properties are:
