an experimental study has been made of the hydrodynamics of a stage mixer-settler to obtain appropriate design information. in this paper several tests were done according to full factorial design of experiments with high reliability, since each test recurs seven times and the results of  them are very close to each other(p=1bar and t=25 °c). sauter diameter in each test is determined with phot...
