Chemical Engineering

this burns alot like gunpowder and gives a very similar effect. what you need is -powder fertilizer read ingredients make sure it has kno3 in it - suger mix it together with a ratio of one part suger to two parts fertilizer this will go bang like nothing you done ever seen. have fun =p

Scope is great!

It is basically a field where the job profile varies from field work e.g. plant operation including refineries, chemical industry, fertilizers industry etc; to design and development e.g. plant troubleshooting, revamp, Comp. aided process and plant design, control engineering etc. etc. (list is very long).

For girls CAD, control engineering, and troubleshooting and revamp kind of jobs (typically named as technical services) are well suited. Operation jobs are rather rough and tough jobs requiring shift duties and plant visits during odd hours, in case of any emergency.

Hope I have provided a to-the point brief answer. In case of any detail needed please mail me at jassa28@yahoo.co.in. ( I am a senior chemical engineer in design area)

Best of luck.

Virtually all synthetic polymers are used in industry.

Biomass is burnt to make electricity in the same way as coal and oil. It does not release additional carbon dioxide into the atmosphere, but its black and brown carbon (ash) pollution contributes to global warming when it lands on snow and ice, and when the particles are absorbed by water vapour droplets in clouds.

A shell and tube heat exchanger will have two fluids flowing through continuously. The fluid in the tube will typically be the important fluid, the fluid you are trying to heat or cool. The fluid in the shell will then be the fluid that is heating or cooling the the fluid in the tube.

Take a steam heat exchanger for example. Steam condenses in shell, while the the fluid in the tube picks up the heat from the steam. And in a perfectly efficient steam heat exchanger, all the heat lost from the steam would be recovered by the liquid in the tube.

But nothing is perfect. A little bit of the steam's heat makes the outer shell hot, and that in turn heats the room. Heat is lost from the steam into places other than the fluid in the tube. So efficiency measures how much of the heat lost by the shell fluid makes it into the tube fluid.

Efficiency (for heating) = Amount of Heat that went toward heating the fluid divided by the amount of heat that was lost by the heating fluid.

So an efficiency of 1 is perfect. For every 1 unit of heat absorbed by the tube fluid, we spent 1 unit of heat from the fluid in the shell fluid.

And if the efficiency is 0.9, or 90%, then for every 10 units of heat that the shell fluid lost, the tube fluid gained 9.

Sometimes efficiencies are as bad as 40%. In this case for every 10 units of heat lost by the heating fluid, 4 units are gained by the fluid.

A slightly different definition of efficiency applies to cooling:

Efficiency = Amount of heat lost by the tube fluid divided by the amount of heat gained by the shell fluid.

Same story, if the shell fluid gains 5 units of heat, and tube fluid loses 4, then the efficiency is 0.8 or 80%.

You need to take up to 4 years of calculus, as well as many science classes in physics and chemistry. Classes in algebra and trigonometry may be prerequisites for calculus.

The turbine flow meter translates the mechanical action of the turbine rotating in the liquid flow around an axis into a user-readable rate of flow. The turbine tends to have all the flow traveling around it. The turbine wheel is set in the path of a fluid stream. The flowing fluid impinges on the turbine blades, imparting a force to the blade surface and setting the rotor in motion. When a steady rotation speed has been reached, the speed is proportional to fluid velocity. Turbine flow meters are used for the measurement of natural gas and liquid flow

Don't know about liquid sucrose.... but the specific heat capacity of sucrose is 0.30. This means that 0.30 calories of heat are required to raise the temperature of one gram of sucrose by one degree celsius.

You sure you don't mean a sucrose solution... rather than liquid sucrose? Seems unlikely to have pure liquid sucrose, and very likely to have a water-based sucrose syrup solution. If that's the case, then it depends a great deal on the concentration of the solution itself.

According to the pdf (link to the left of this answer), the specific heat of sucrose solutions is:
40% sucrose sugar syrup: 0.66
60% sucrose sugar syrup: 0.74
However, note that it's in very strange units: Btu/lb . °F

Normally you can just refer to the polymers just as proteins, but if you want to be specific, you can say polypeptide, thereby excluding amino acids, dipeptides, and oligopeptides. The monomers of proteins are amino acids.

(Sack of Barite = 100 pounds)

(Cubic foot of Barite = 150 pounds)

(Density of Barite - 2.087)

*Sucrose (fructose, glucose) *Maltose (glucose, glucose) *Lactose (galactose, glucose)

* = disaccharides

()= monosaccharides

All are sugars which equal carbohydrates

other examples are corn syrup, sorbitol, glycerol, dextrin, starch...

You can make your own battery, or you can use a generator of some sort.

To make a battery, you need an electrolyte of some sort and electrodes from opposite ends of the period table. You would likely use zinc for one of the electrodes and copper or carbon for the other. You could use citrus fruit or potatoes for the electrolyte medium, and place the electrodes into them.

For a generator, you would need to create moving magnetic fields inside of coils of wire. You would have to create the movement at a steady rate, and use circuits to regulate the voltage and current produced.

Silver is used as a low resistance conductive material. Contactors and relays contact points are made of copper and are silver plated to obtain the lowest resistance between the moving contact faces.

Assuming you have binary components the McCabe Thiele Method should be used. Otherwise a process simulator such as Aspen, Pro/II, and/or KGTower should be used.

Well.. Its a small n initeresting question but the answer is too lengthy for this.. I will try briefing on it. Crude oil procured contains many impurities like salts, metals which need to be taken off. Its been taken to desalters and then to the main crude column. In fractionator, the components get separated depending on their boiling points. The bottmom of the fractionator is taken to vaccum column. The vacuum maintained will be approx 15- 20 mmHg at the bottom of the column. Lighters generated in main column are aondensed and used as naptha. The different cuts like kerosene and diesel are routed to respective hydro treaters. The heavier portion (higher C-H) are considered for either hydro cracking or hydro treater. In hydrotreater the main reactant is Hydrogen which is used at very high pressure and temperature which helps in denitrification and desulfurisation respectively.

No, brass is a metal that will stay for thousands of years in landfills and rubbish dumps without breaking down.

Process engineering helps obtain the specifics of a certain industrial process. In the biotech industry, the quality of the final product has a huge bearing on the right physical and chemical conditions being maintained.

Therefore, the industrial process has to be engineered in order to obtain product starting from raw material.

thermosetting plastic becomes hard when heated and deteriorates by excessive cross linking and thermoplastic becomes soft and can be moulded into any shape.

I know it is an additive used in gasoline and some other petroleum products. Do a google search on it. The above answer is incorrect. It was a refrigerant and aerosol spray propellant until its manufacture was discontinued in 1995. It was usually sold under the brand name Freon-12.

Yes, in olden times, when cars used lead net in the smoke valve of the cars, at that time, it released a lot of smoke into the air. If one wanted to dispose it, he needed a lot of effort to do so. So, lead vapour is a non- biodegradable pollutant. Now a days too burning lead is poisonous thing and is a hateful thing to do to the workers. It releases CO2 in the air also.

By evaporating the water out, which precipitates the sugar back into its crystalline form.
