Question

Why farmar sprayed cetyl alcohol in water why?

Answer 1

The farmers spread a layer of cetyl alcohol on the surface

of a farm lake to stop evaporation of water. Research shows that mono-layers of

cetyl alcohol help to reduce up to 30 percent of the evaporation of water from

open water storages.     Different

techniques are used for this. They are:

1. Mooring gauze rafts on the surface of the water. These

contain solid pellets of cetyl alcohol.

2. Drip dispensing the cetyl alcohol solution in a volatile petroleum

solvent.

3. Dusting the surface with dry, finely powdered cetyl

alcohol.

The third method is very efficient.
