Drying speed of salt particle

  • #1
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 (Lets just assume that is is NaCl)
- Relative humidity
- Air speed around the particle
- Temperature

Or maybe someone just made a measurement.

I doubt they ever do dry out ... sodium chloride is hygroscopic . It absorbs moisture from the atmosphere when the relative humidity is above 75%

But they must dry out when the humidity is below 75% In my case when the air enters a ventilation duct where the air is heated slightly.

Look under "sea spray", or "aerosols", and see if you can find out some information for your inquiry.
