A stirrer is used to mix chemicals in a large tank. The shaft power ? supplied to the stirrer

blades are a function of stirrer diameter D, liquid density r, liquid viscosity m, and the angular velocity ? of the spinning blades. Use the method of repeating variables to generate a dimensionless relationship between these parameters. Show all your work and be sure to identify your Π groups, modifying them as necessary.
