Flow in pipe - Pipe Flow Calculations

Flow in pipes is considered to be laminar if Reynolds number is less than 2320, and turbulent if the Reynolds number is greater than 4000. Between these two values is "critical" zone where the flow can be laminar or turbulent or in the process of change and is mainly unpredictable.

Difference Between Hydrometallurgy and Pyrometallurgy ...

February 16, 2020 Posted by Madhu. The key difference between hydrometallurgy and pyrometallurgy is that in hydrometallurgy, we use an aqueous solution to extract metals from the ore, whereas in pyrometallurgy, we use high temperatures to extract metals from the ore. Hydrometallurgy and pyrometallurgy are two main branches in industrial chemistry.

The first rule deals with the conservation of mass. The total flow of the material into the process plant equals the total flow out. The second rule relates to the quality or grade of the concentrate product. In practice, it is impossible to produce a concentrate consisting of only one mineral. The third rule is a corollary of the second.
