WebNov 22, 2011 · Growth was compared within ranges for power input, mixing time, impeller tip speed and Reynolds number. Maximum specific growth rates were observed for AGE1.HN cells at a common mixing time range of 8 - 13 seconds for all cultivation systems. WebTip Speed And Gap Shear Rate, γgap, (s-1) Tip speed, V tip (m/s), can be used to evaluate the kinet-ic energy imparted to the fluid from the tip of the rotor-blade as well as determining the shear stress and rates imparted to the fluid. A direct function of V tip is the shear rate in the gap between the rotor and stator, γgap, (s-1). The ...
