Question

What is Reynolds number?

2. What are the three types of fluid flow based on Reynolds number?

3. What is the difference between free settling and hindered settling?

4. Differentiate compressible and incompressible fluid.

5. Mention any four unit operations involved in ceramic industries.​

Answer 1

Answer:

1. The Reynolds number is the ratio of inertial forces to viscous forces. The Reynolds number is a dimensionless number used to categorize the fluids systems in which the effect of viscosity is important in controlling the velocities or the flow pattern of a fluid. Mathematically, the Reynolds number, NRe, is defined as.

3. Hindered settling: In classification, when the minerals settle in a thick pulp, as opposed to free settling in which the free particles fall through fluid media. Free settling :As opposed to hindered settling in classification, free fall of particles through fluid media.

5. Traditional ceramic raw materials include clay minerals such as kaolinite, whereas more recent materials include aluminium oxide, more commonly known as alumina. The modern ceramic materials, which are classified as advanced ceramics, include silicon carbide and tungsten carbide.
