제목 Power Consumption of Pitched and multi-stage impeller in a turbulent region  
초록 Power input in stirred vessel is especially important in the design of mixers, as well as the evaluation of mixing processes. A type of baffles in mechanically agitated vessels and power employed are major factors that determine the stirring efficiency in a large scale, multi-step processes. In the present study, power input in the totally baffled agitated vessels was compared systematically in connection with several previous studies and adequate power input correlation was found to be : Np(pitch)=(θ/90°)Np(90°)Power number correlation was dependent upon the distance of among the impeller in the agitated vessels, as follows :  
Np=7.09(np)0.7(b(double)/d)(H/D)0.18,  np0.7(b(double)/d)2
