heat it

Gas or liquid passed through bottom of the column and the solid particles from the top is fluidized below the maximum fluidization velocity with regeneration of continuos stage.

Heat it up, the modulus will increase from 28 GPa to about 70-80 GPa

Oxidising is losing eletrons

Neither!

To change a face-centered cubic (FCC) structure to a body-centered cubic (BCC) structure using nanotechnology, one can manipulate the material at the nanoscale through techniques such as epitaxial growth or phase transformation. This involves controlling temperature and pressure conditions to induce a transformation, often utilizing nanoscale catalysts or templates to guide the reorganization of atoms. Additionally, advanced methods like mechanical strain or irradiation can facilitate the transition by altering the atomic arrangement. These processes require precise control over synthesis conditions to achieve the desired crystal structure.

A batch dryer is a type of industrial equipment used for drying bulk materials, such as grains, seeds, or biomass, in discrete batches rather than continuously. It operates by loading a specific volume of material into the drying chamber, where hot air or other drying mediums are circulated to remove moisture. Once the drying cycle is complete, the material is removed, and the next batch can be processed. This method is often used for its efficiency in achieving uniform moisture content and is common in agricultural and food processing industries.

then answer it now..

in a grit chamber mixing of grit takes place.after grit mixing only organic matter remains

People who do coding comes in Front end design and remaining comes in backend ..........

Front end includes rtl description,synthesiser,verilog/vhdl entity,simulator.....

Back end includes floorplanning,place & route,packaging,testing...

Throughput andflowrate both express the quantity or a substance per unit time passed through a specific volume. There are two notable differences though. They are that flowrate is usually only used when referring to fluids and throughput is more suitable when considering the feedstock charged through process equipment not just conduit volumes.

Qh (M3/hr = Fb*Fpb*Ftf*Fpv*Fg*Fr*Y*Ftb*Fa*sqrt(Hw*Pf)

Plastics cost was very less . Plastic bags and plastic boxes are use for many useful for many things.

A Counter-current flow has more advantages as comapared to a co-current flow.

it is difficult to remove the scales.

we cannot use scale forming fluid through the shell because if we pass, the scales are formed and it corrodes the shell.

Enthalpy mathematically is the sum of the internal energy and work done in a process.internal energy is the sum of the kinetic energy,potential energy,vibrational energies etc

Packing factor is a dimensionless ratio that describes the amount of volume that a substance takes up in a particular volume. For example, if you have a box and you fill it with balls, the volume of the box is taken up by the balls and by the space in between the balls. The packing factor would be (volume of the balls)/(volume of the box). Packing factor is, among other things, relevant to the arrangement of atoms in different crystallographic structures.

Please have a look at the site below, it gives a very good explanation of the different uses of MEG and TEG. Some addition: Because the possible water content goes up in the order MEG<DEG<TEG, I'd expected TEG to have a better affinity for water, but it doesn't. The reason why TEG is used, is because it has a lower vapor pressure, so you will lose less in your process. Tetra EG would be better, but it's more viscous, so it would cost more to pump it around. You need to take into account more properties than only the hygroscopicity. Apparently, MEG is preferred for the low-temperature process with MEG injection, but it's not even cheaper! I'd say this satisfies my similar question for about 90%. http://www.jmcampbell.com/march-2007

one main reason of treating cooling tower water is the presence of substances that can cause corrosion. what we do is eliminate the corrosive agents.

well corrsoion is one of the reasons,it may cause chocking,blocking in the pipes which then will restrict the flow and cause severe damage

Bridge wall is wall between rows of tube. Usually in box heater.

Bridge wall temperatur in temperatur leaving radiant section after heating radiant tube before heating convection tube.
