How do you cover up the smell of varnish in a transformer manufacturing factory?
OSHA says you must vent and scrub air, hope you are doing so.
When handling hazardous chemicals where do you find information for your safety?
An container of hazardous materials must state safety instructions on the label. Any such hazardous materials must have been assessed by the company or employer before using in any manufacturing process, and any relevant safety information must be passed on to the employee as part of the training. As following safety regulations in the workplace is compulsory by law (at least in the UK), anyone (employer or employee) could find themselves in serious trouble should an accident occur. Addition note: Not only is the correct and safe use of hazardous materials important, but just as important is the safe disposal of any hazardous waste.
Why does the diameter of distillation column vary at different location?
A distillation column has flows of materials going up and down the plates or packing. The flow across each plate or section of packing is an essential factor in the optimization calculations and design. Diameter is one of these considerations. Since columns have "heavies" traveling down and "lights" moving up and the division between these components may not be even, the top and bottom flows may be quite different, and the optimal column diameter must be adjusted at different locations along the length. Add to this the introduction of a feed stream at some point in the mid-column and the flows are altered again. But why be concerned about this? Columns are often constructed of expensive alloys, glass lined, or heat treated to avoid erosion, corrosion or stress problems. Minimizing the column size minimizes the cost. Along with quality of product, cost is an optimization factor.
How many carbons are there in crude oil?
A tear-drop shaped piece of feces which dangles from the rectum while defecating. To knock it off you must rock back and forth and from cheek to cheek to dislodge it from your sphincter.
What are chemical engineers responsibilities?
The Duties and Responsibilities of a Chemical Engineer:The role that a chemical engineer plays in today's world is an important one to put it quite simply. There are many responsibilities which a chemical engineer must undertake on a daily basis and various specific duties which must be carried out as well. It is important to look at these items to determine why the role of chemical engineer is so important and whether one is suited for a job of this type.What Is a Chemical Engineer?An individual who works as a chemical engineer is responsible for manufacturing chemicals and developing processes for doing so. The chemical engineer will also design chemical plant equipment as well. Some of the products which the chemical engineer is involved with developing may include rubber, plastic, gasoline, cement and paper, just to name a few.General Responsibilities of a Chemical EngineerThe chemical engineer is a person who has multiple job responsibilities under their charge. One who works as a chemical engineer must do a lot of research in the beginning to determine the best way of producing certain products. Along with researching the issues, the chemical engineer must design programs, machinery and processes which will allow the products to be manufactured. The chemical engineer must also perform a multitude of tests along the way to ensure that everything is going according to plan. Lastly, one who is a chemical engineer must consult with numerous individuals to ensure that their job is done to the best of their ability and the desired outcome is reached.Specific Duties of a Chemical EngineerBeneath all of the general responsibilities listed above, a chemical engineer must engage in numerous specific duties on a daily basis. The first duty which the chemical engineer is responsible for completing is research. The chemical engineer must take careful steps to ensure that what they are looking to manufacture and how they are looking to manufacture a product is the right avenue to pursue. The way to resolve this issue is by doing a lot of research on a variety of topics relating to chemical engineering.The chemical engineer is also responsible for designing a variety of items and this is a very important duty which they must complete. A chemical engineer must design various items such as measurement and control systems, chemical manufacturing equipment and chemical manufacturing processes. This is a major duty on the part of the chemical engineer and one which must be carried out with preciseness at all levels and stages.A chemical engineer must also engage in a wide array of analyses. The things which the chemical engineer must analyze include test data, engineering design, design problems and research findings. The chemical engineer must take painstaking measures to adequately analyze these items as the outcome of the project could very well depend on the analysis which is undertaken by the chemical engineer.One who is an engineer must develop certain procedures and policies as well so that there will be smooth operations all the way around the board. Various procedures and policies such as safety procedures, data tables and employment policies may all be in the hands of the chemical engineer. A senior level chemical engineer will have more to do with regard to developing policies and procedures within the company or corporation.The preparation of multiple reports is also in the hands of the chemical engineer. The chemical engineer must prepare data which specifically details the findings of certain tests and evaluations. These reports can be text or tables depending on the type of report which is needed.A chemical engineer will also deal with other individuals a great deal. The reason for doing so is to relay the results and findings as well as oversee other chemical engineers and related workers in their field. From time to time, chemical engineers must lecture to their peers and the general public regarding their job and role in society.Beneficial Attributes Which All Chemical Engineers Should PossessThere are many positive attributes which chemical engineers should have in order to make their job role progress more smoothly. First and foremost, a chemical engineer must have a keen scientific mind. As chemistry, physics and engineering are all part of the daily job role of a chemical engineer, it is imperative that an individual who has this profession possesses a keen scientific mind.Superb analysis skills are necessary for a chemical engineer to possess if he/she wants to be the best in their field. There are so many documents, processes, diagrams, tables and equations which a chemical engineer must analyze on a daily basis that it should be no shock that wonderful analysis skills are a must.A chemical engineer will also find it beneficial to have good research skills. Frequently a chemical engineer will need to find out certain information regarding their projects and will have to perform quite a good deal of research in order to obtain the results that they need. This is why valid research skills are handy for a chemical engineer to possess.Another attribute which a chemical engineer should have is a precise nature. Anything that is scientific warrants preciseness by those working in this field. A chemical engineer is no different. Since the chemical engineer is using various types of sciences to complete their job, it is important that they are precise. Not only will this make their job easier but it will also make it less likely that they make a mistake in the calculations and the final product as a result thereof.One who is a chemical engineer should be able to pay attention to detail. They need to be able to pick up on certain aspects of the engineering process and determine if something is working and if not, how they will fix it. By paying attention to detail and having this quality, a chemical engineer will find it easier to pick up on any potential problems which may occur along the way.ConclusionOne who is a chemical engineer will find that the role which they play is important and their work needs to be done as correctly as possible. If one is interested in pursuing a chemical engineer profession, they will find it valuable to consult the aforementioned items to see if this job is for them. In addition, if the interested party is good with details, precise in nature and has an excellent scientific mind, then obtaining a job as a chemical engineer might just be the best bet.
Must the flow of a compressible fluid be treated as compressible?
Yes, the flow of a compressible fluid must be treated as compressible when the fluid's density changes significantly with changes in pressure or temperature. Incompressible flow assumptions cannot accurately model such fluid behavior.
In order for a material to be compressible there must be space between the particles which states of matter will be in compressible?

Why is brake fluid used in car brakes?
To start off, a fluid is used in the brake system because fluids are not compressible, so it can transmit the force applied by your foot to the brake system. This is the reason brakes must be bled of air. Since air is compressible it will increase the distance your foot must travel before the force of the fluid can do it's job. Brake fluid is specifically designed for brake systems because it can sustain high pressure, lubricate components, and withstand high temperatures.
Is necessarily a conjunction?
No, "necessarily" is not a conjunction. It is an adverb that indicates something that must happen or be the case.
Is oxygen compressible?
All gases are compressible. Depending on their state. Oxygen can be a gas, a solid or a liquid. Liquid oygen (very very cold) would not be compressible, solid oxygen (frozen) would not either but as a gas at standard conditions - room temperature and pressure - it can be compressed. For example, compressed oxygen is used in emergency vehicles to keep people alive if they are injured or sick. It is extremely flammable, almost explosive so no smoking near a compressed oxygen gas cylinder, OK?
