Pressure is an important part in distillation because boiling points of different components to be separated depends on pressure, for normal distillation pressure is kept as 1 atmosphere but for components with high boiling points instead of rasing the temperature pressure is lowered till the vapor pressure of the components to be separated, hence the temperature to be raised becomes less, for example in vaccum distillation.

Power generation plants typically require mechanical and electrical engineers as a majority of the workforce; however there are a few areas that a chemical engineer can get involved in. Any treatment processes within the plant, such as air, water, etc. can be done by a chemical engineer. If the power plant produces chemical wastes, such as tritium in a nuclear power plant, this isotope has to be removed in a process containing distillation columns and other chemical engineering processes, making chemical engineers ideal for this position.

Some chemical engineers can work within risk assessment and can do work to determine risks within the plant and how best to prevent them.

A low flash point in diesel is caused by contamination of the diesel with lighter petroleum products such as kerosene or gasoline. Drawing more lighter products out of the fractionation tower could reduce contamination of the heavier products. Improving fractionation and improving diesel product stripping performance will raise the flash point.

An estimated 250,000,000,000,000 a year.

the upstream of a pipe is its inlet and the downstream is its outlet

****if your talking about broadband/internet speed*****downstream is taking information from the internet.(downloading) upstream is putting info on the internet uploading

It does give players an advantage such faster swimming speeds, more reach and big hands. However, not all water polo players are tall. I know a someone who was 3rd team all-american and she is barely over 5'6".

This type of column is used by ephedrine manufacturer. Please refer Kreps biochemical & industries, Nellore, Andhra pradesh, India.

Free carbon in cast iron refers to carbon that exists in its elemental form within the iron matrix. It appears as graphite flakes or nodules, contributing to the material's unique properties, such as high fluidity during casting and improved machinability. This free carbon distinguishes cast iron from other metals.

As rubber band is made up from rubber, it possess properties of rubber.

main property of rubber is "ELASTICITY" i.e. whenever you stretched rubber or rubber band it gets stretched & when you released it, it will gain it's original size & shape again.

A promising polymer that could be grown sustainably and that could possibly replace typical plastic is cellulose. Cellulose is a organic polymer produced within plants and there is research in developing some stable products from this resource; however, a lot of research still needs to be done within this area.

Some methods of trapping carbon dioxide are: electrochemical reduction, cooling it into a liquid, and passing the gas through an alkali.

Brine plant will gives us the temparature below zero degrees. but where as in chilled plant the temparature above zero only

The best way to make a fire burn hotter is to use the hottest burning logs that you can. Oak, Ash and Black Locust burn very hot. Feed them into the fire along with fast burning wood such as Maple to keep the fire raging. If you do not burn a fast burning wood with the Oak and Ash, they will burn very hot, but very slowly. The object is to make as many red hot coals from the Oak and Ash at the base of the fire as possible. That is where the heat from your fire will come from and the more coals the hotter the fire will feel. Additional information for those seeking info on other than fireplace fires It also helps to make a low side base surrounded by something and make it narrow at the top, so that all the fire is more focused in one spot. using all these ideas was what made the first copper, silver, and gold things. you may ask yourself how can you make a fire so hot that it burns metal but not whats surrounding it. rocks, carefully build rock kilns.

That depends on the exact circumstances. For example, in electrical circuits, power = I2R. However, since the current, in turn, depends on the voltage and the resistance, it is better to express this as V2/R. For mechanical energy, power is basically speed times force.

The main difference is specilization. I am a chemical engineer myself, and we have the option of specializing in a wide variety of degrees, such as genetic engineering. Note that chemical engineering is a very broad field dealing with polymers, metallurgy, biology, environmental chemistry, and the list goes on. Genetic engineering, in short, is really a specialization of chemical engineering to specifically biological chemistry.

It depends at what temperature. If we assume that it is at its boiling point already, then you do the equation. Q=MH(f). Q= heat, m=mass, and H is the feat of fusion. For water it is 2260J/g. So do it like this. Q=1000mL * 2260J/g. You need 2260 kJ to heat 1L of water at its boiling point.

you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy. you take pipes from the fire to the chest and melt ice over it the cold water will keep it cooled down dawg. Fo Sheezy.

When a cold object and a hot object are in direct contact (touching) heat will be transferred through thermal conduction.

Normally, heat transfer processes are categorized as thermal conduction, radiative transfer or convection.

Heat transfer through thermal conduction is the direct transfer of kinetic energy from one molecule to the nearby molecules. Because temperature is directly proportional to kinetic energy, interactions between neighboring particles exchange energy and that exchange energy gradually works it way from the higher temperature regions to the lower temperature regions. The process of the temperature becoming the same is called thermal equilibration.

Convective heat transfer occurs in fluids. If a gas, liquid, or other fluid, changes in fluid density change the buoyancy and will cause fluid to flow (a process called convection) and the heat contained in the warmer fluid is transferred to a new location by the physical movement of the fluid.

Radiative transfer occurs when a hot object radiates electromagnetic energy. While the sun is an obvious source of electromagnetic energy, it is also generated in smaller amounts by any object. The hotter objects radiate more electromagnetic energy and the cooler objects absorb it. This radiative transfer is important but not as noticeable usually as the other two. It does occur between objects whether they are in direct contact or not, but is usually so small as not to be important of the objects are touching.

HYDROGEN & He cant be liuefied because their atomic Masses are small .

second reason is that intramolecular forces are not present in helium and they cannot form covalentbond London forces are weak then inter molecular forces so less energy is required to overcome these forces and gas cannot be cooled.

The preparation of uranium from ores is a long chain of chemical and physical processes.

Kevlar is a synthetic fiber with an extremely high tensile strength. It was created in 1971 by DuPont Chemical group.
