The spin rate of a tennis ball determines the aerodynamic forces acting on it. In turn, the spin rate is affected by the aerodynamic torque. If the torque depends on flight speed V, density p, viscosity , ball diameter D, angular velocity w, and the fuzz height, hy, find the important dimensionless variables for this case. Use V, p, and D as your scaling (repeating) variables.
