When a sphere of diameter d falls slowly in a highly viscous fluid, the settling velocity, V, is known to be a function of d, the fluid viscosity, μ, and the difference, , between the specific weight of the sphere and the specific weight of the fluid. Due to a tight budget situation, only one experiment can be performed, and the following data were obtained: V = 0.42 ft/s for If possible, based on this limited amount of data, determine the general equation for the settling velocity. If you do not think it is possible, indicate what additional data would be required.
