When a bubble in the ocean bursts water drops are thrown into the air. How fast do these water drops dry out creating solid salt particles? There must be a formula for calculating this and I am guessing that the following variables must figure in the formula:
- Droplet size
- Salt concentration...
The properties of the liquid should be such that the liquid can be standing still in a system of tubes without separating into fractions even after weeks of zero motion. The liquid should also have a lifetime of at least one year and it should have as low a viscosity as possible. One possibility...
I am looking for a Bingham plastic that is not a suspension. It can either be in the form of an additive to water or a non conductive chemical. The liquid should have a yield stress of 150 Pa to 250 Pa. What liquid could be used here? Are there companies who tailor make these kind of liquids?
Hi Chester
I have already been googeling for hours on question 2 and 3 but the only thing that comes up is general stuff about ketchup or specific stuff about solving the governing equations or simulations. I have so far been unable to find a nice catalogue from a supplier producing a liquid...
Hi Chester
You already answered the first question for me. I was googeling yield pressure and getting nothing. The right words were the ones you used in your reply to me:)
I still need answers for the two last questions.
The formula is:
Found in this PDF...
Yes I am asking how much pressure difference is required for flow. I think that I have read somewhere that a larger initial pressure is required for small diameters.
I have three questions.
1. How do I calculate the yield pressure for a Bingham plastic in a tube if I am given:
Length of tube
Diameter of tube
Yield stress of liquid
2. Is it possible to engineer a liquid to have a specific yield stress ?
3. What kind of material would be suited for...
