Chemical Engineering

Function - It adds the pressure to the feed water before it entyers into boiler feed pump suction

Advantage - Ensures high margin NPSH A for boiler feed pump spinning at high rpm (5250Rpm)

Drive for booster - Normally @1450 rpm

Type of impeller- Mostly preferred Double suction

Venturimeter is the short pipe having two conical parts and portion of uniform cross section between these two parts.

process is a set of operation for example in a sugar mill the processing involve

1. bringing out juice from sugarcane.

2. heat them.

3.refine them.etc.

here process is the combination of all of the above stated tasks (1,2,3,).

on the contrary, each of the tasks of a process is operation for example the task

1,2,3, each are operation.

The difference between impulse and reaction turbine goes here...... 1) In case of an impulse turbine the pressure remains same in the rotor or runners, but in case of reaction turbine the pressure decreases in runners as well as stators also. 2) In case of impulse turbine the pressure drop happens only in the nozzle part by means of its kinetic energy. In case of Reaction one the stators those are fixed to the diaphragm act as a nozzle.

SPEED OF TURBINE IS DEPEND ON THE WATER PRESSUR(7BAR)

It is common practice to specify the pump suction line one size larger than the pump discharge line in order to increase the Net Positive Suction Head available (NPSHA) to the pump. A smaller suction line the same pipe size as the discharge line would result in more pressure drop in the suction line and reduce the amount of head available to the suction side of the pump. This in turn would result in an operating point closer to cavitation of the pump.

Before any work is done on the machine you must ensure that the correct risk assessments are in place and have been fully read so you're aware of the dangers that the machine possess.

When working with machinery you should always ensure that you're competent to use it, do not use equipment that you're not trained to use. When using machinery always be aware of where you're emergency stop buttons are and where there are any areas in which you could be caught, entangled or trapped in moving parts. Always ensure that you remove any lose clothing or jewellery and tie back long hair. Ensure that all machine guards are put in place before using the machine.

When using an automated welder, you should always ensure that you wear the correct P.P.E at all times. Always wear a long sleeve welding jacket to cover any bare skin to stop UV burns. Use a welding helmet or face shield when the arc is in process to protect your face from UV burns and your eyes from "arc eye". Wear safety glasses at all times to ensure that your eyes are protected from any particles or debris that my fly into your eyes. Before, during and after welding ensure that there are adequate welding screens around the equipment to protect others in the vicinity from the welding arc. Also if necessary use the correct fume extraction equipment to remove any unwanted fumes, this will not only protect your but others in the vicinity.

On completion of any welding activity the machine must be shut down in the correct manner, to avoid any malfunctions and damage to the software. You should dispose of any waste, i.e. filler wire, materials, in the correct manner that applies with the COSHH regulations.

1. It is used for flow measerment with minimum head loss.

2. It is used in industries for flow measerment of chemicals.

3. it is also used in the airoplane for measurment of speed of plane.

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".

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.
