Physical aspects - Instability mechanisms - creaming and sedimentation
3 important questions on Physical aspects - Instability mechanisms - creaming and sedimentation
Why is molecular weight important to decide if creaming or sedimentation occurs?
Low density (e.g. Oil droplets) --> cream
Higher density, solid molecules --> sediment
Higher density, solid molecules --> sediment
What is the Buoyancy force?
A force going upwards from the droplet.
Fb = -mg = -pVg
Fb = -mg = -pVg
Which 3 factors decrease the velocity?
- Density difference in smaller
- Radius of the particle is smaller
- Viscosity of the continuous phase is larger
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
