Study Notes
Flow Patterns in Mixing
- Axial (longitudinal) flow exhibits a flow pattern where the liquid flows parallel to the shaft.
Sedimentation Rate
- Viscosity of the liquid reduces the sedimentation rate of suspended particles.
Radial Flow Pattern
- Involves the impeller pumping the liquid from the surface to the bottom.
Mixing in Tanks
- Axial flow impellers are commonly used to mix liquids as well as liquids and solids in tanks.
Tangential Flow Pattern
- Involves the liquid flowing at right angles to the shaft.
Rotational Flow Pattern
- Involves the liquid flowing in a circular path around the shaft.
Impeller Mixers
- Propeller mixers commonly involve radial flow patterns.
Mixing Methods
- Axial flow is the most common method for mixing liquids as well as liquids and solids in tanks.
