A mixing time of 29 s was measured for a 4.5-ft baffled tank with a 1.5-ft six-blade turbine and a liquid depth of 4.8 ft. The turbine speed was 75 r/min, and the fluid has a viscosity of 3 c_P and a density of 65 Ib/ft3. Estimate the mixing times if an impeller one-quarter or one-half the tank diameter were used with the speeds chosen to give the same power per unit volume.
