Physical data
Divergence
Measure of imbalance. Scale component is using pressure field
Incompressible fluid - have not “scale factor” still have : swirl , shear and translate factors
| Divergence | |
|---|---|
| - | Clump them together. |
| 0 | For Incompressible fluid |
| + | Cause particles to spread out |
Viscosity
Measure of its resistance to deformation. All fluids are viscous somehow.
| Viscosity | value at CentiPoise (at room temp ~21°C (70°F)) |
|---|---|
| Water | 1 |
| Milk | 3 |
| Motor Oil SEA 10 | 85-140 |
| Motor Oil SEA 30 | 420 - 650 |
| Motor Oil Castrol | 1000 |
| Honey | 3000- 10 000 |
| Chocolate | 25 000 |
| Ketchup | 50 000 |
| Mustard | 70 000 |
| Sour Cream | 100 000 |
| Peanut Butter | 150 000 - 250 000 |
| Sanitary Silicon | 5M - 10M |
Surface tension
Tendency of liquid surfaces to shrink into the minimum surface area possible.
Property of warte molecules that are attracted to each other (cohesion). it is on surface, where molecules have space to stronger their bonds forming a tension that is absent in rest position. Measured in: Pa * s.
Creating the surface pressure field. Fight against gravity trying to put particles in to drop.
Function of curvature of shape. It try minimise it where is bigest. Create oposeing forces on large changind curvature.
Sphere have no surface tension.
