Notes:
Power data for dispersion of air in liquids by means of a six-bladed flat blade turbine are presented in the form of a logarithmic plot of actual power consumed against a function of speed, impeller diameter, gas flow rate, and impeller power characteristics. The data are those of Michel (7), Bimbenet (2), Sachs (12), and Oyama and Endoh (10).Turbines of from 3- to 8-in. diameter were run in tanks of from 6.5- to 18-in. diameter, with the D/T never exceeding 0.47. The fluids tested covered a density range of 0.8 to 1.65 g./ml. and a viscosity range of 0.9 to 100 centipoises.Data are also presented on dispersion of air in a 50% by volume batch of carbon tetrachloride in water and dispersion of air in a suspension of Alundum particles in water, and compared with data on water in a similar system.The qualitative effect of a surface active agent is demonstrated in a comparison of data for a 0.1% by weight mixture of Pluronic L-62 in water with data for pure water with the same apparatus.
