evaporation rate for water droplets
evaporation rate for water droplets
(OP)
I want to know if the small water droplets evaporate much faster than the water in open vessel on heating.What is the theory and formulas behind it.
We are facing a problem.When the water,air spray applied to coke and sinter,it is vaporized.The high temperature of these materials were unknown.Average temp. is nearly 110 degree centigrades.This is about dust containment.

RE: evaporation rate for water droplets
One of their key learnings is that for droplets larger than about 50 micron diameter, evaporation is a surface function. Below that it is a body function and evaporates based on droplet volume instead of area and evaporation takes significantly less time with small drops.
In your dust containment example it sounds like you want to reduce the rate of evaporation so you should use big droplets.

There are lots of different atomization techniques. There will be a balance between evaporation loss and over watering.
