The interrelations among the discharge flow rate, the mixing power and the mixing time in the fully turbulent range in mixing vessels are investigated experimentally with paddles and baffle plates of various dimensions covering from non-baffled to fully baffled conditions. The discharge flow rate number is correlated as a function of the paddle dimensions and the baffle plate dimensions. The relations between the discharge flow rate number and the power number under incomplete baffle conditions are obtained in two cases. If the baffle condition level is fixed, the power number is proportional to the discharge flow rate number for the various paddles. If the paddle is fixed, the power number is proportional to the square of the discharge flow rate number for various baffle conditions. The mixing time is proportional to the time required to circulate the discharged liquid once, and the number of times of circulation to reach mixing is correlated with paddle dimensions, regardless of baffle conditions.
