It is mostly carbon monoxide and nitrogen gases which has some heating value. So it is typically recovered and mixed with natural gas, &/or coke oven gas and used in boilers for steam or other steel heating furnaces for further processing of steel.

Rubber is light,smooth and rubbery.

water can cut through glass but only when at a very high speed and a thin stream

Many of the calculations done by a working ChE involve Thermodynamics, Physical Chemistry and Kinetics and Catalysis. It's not just adding and subtracting by any means. A firm background in Math is required.

I suggest that you find a copy of Perry's Chemical Engineering Handbook in the library, and thumb through it. You will get an feel for some of the work done.

energy is economised since the evaporator at alower pressure heats the following effect

Most ink is a simple suspension of pigments or dyes in water, though much more complex variations exist.

Most modern forms of ink are not significantly affected by moderate changes in temperature, but there are a few effects possible to varying degrees depending on the particular ink.

Like all fluids, a decrease in temperature increases viscosity, affecting the flow of ink.

An extreme decrease in temperature will, of course, freeze the ink.

Extremely high temperature will, of course, vaporize ink.

Low, or freezing temperatures as well as high temperatures can result in altering properties of the suspended particulates causing them to precipitate out and making the remaining dissolved or suspended particles less effective as coloring agents.

It is unlikely that increases in temperature, below boiling, will induce chemical changes beyond those affecting solubility mentioned above, but this may be a rare event in some specialized formulations.

There are many dyes that are affected by age, light, oxygen and temperature and are therefore inappropriate for use as ink, but that does not mean that such deficiencies are always properly avoided by all manufacturers.

Because they can be colored, molded, cured and have reasonably good mechanical properties.

Currently, the United States consumes 19.6 million barrels per day, of oil, which is more than 25% of the world's total.. As a result, the U.S produces one fourth of the world's carbon emissions. Despite predictions that the U.S. will exhaust it's supply of oil in as little as forty years, the demand is on the increase, and is predicted to continue increasing, because of the ever increasing population. Increase in resource consumption is caused by three factors: population growth, new uses found for a resource, and increase in demand for a resource to increase living standards. The rate of consumption for oil is increasing at a rate of about 2% yearly

Setting aside heat capacity and other considerations, it will be the metal which can conduct the heat into itself the fastest. The property of a material that speaks to how fast it can transfer heat is called thermal conductivity by chemists, physics and engineers. Silver, copper, gold and aluminum top the list (in that order). A link is provided to the rest of the elements listed by thermal conductivity, and notice that the list starts with the least thermally conductive elements and goes to the most thermally conductive, which are at the bottom.

If an analog oscilloscope is used the actual visual performance of a circuit can be displayed. The limitation is hi frequency. A digital scope will outperform an analog scope in digital however the display is fabricated by hi freq chopping. Another scope is a memory scope whereby a sample is taken for further study of a signal it will not change but slowly decay. ALL OS THESE ARE APPLICATIONS NONE IS BETTER THEN THE OTHER

Conduction is heat transfer by bringing two systems at different temperatures into physical contact. The molecules of the warmer system bang against the molecules of the cooler system more energetically than vice versa, consequently the energy of the warmer system gradually transfers to the cooler system until they come into thermal equilibrium (same temperature). You get conduction through a system if the edges of the system are at different temperatures.

Convection occurs when flow of a fluid at a higher temperature into a fluid of lower temperature. This can either be "forced convection" - requiring a pump or fan, or "natural convection". Where the movement is due to buoyancy effects due to the difference in density between warmer and cooler fluids; as air or liquid heats up, it expands and becomes less dense, which causes it to rise. It is replaced by cooler air or liquid, which is then heated as well.This is why we heat liquids from underneath, and why your house will be warmer if your heater is on the bottom floor.

Radiation is the flow of energy as waves through space (and, in some cases, matter). Some examples of radiation are visible light, radio waves, and radiant heat. That's how the heat of the sun gets to us.

• With the help of pH meter we can get the nature of any liquid rather it is acidic or basic.
• Gives a numerical value
• Simple to use
• Exact pH

The absorption of food is a complex mechanism. When the food substances have been so altered by the enzymes in the duodenum that they now consist of minute's fragments which can readily be used by the body, they are transported to the next two sections of the small intestine, the jejunum and ileum. It is principally here that usable components are taken up by the body. They are absorbed. Absorptions

in these sections of the small intestine proceeds rather like sorting out specific parts from a conveyor belt. Individual substances are selected along the entire length of the small intestine and transported through the wall of the circulatory system.

Naturally, if the absorption through the wall of the small intestine into the bloodstream is disturbed, the whole digestive system soon ceases to function. This has repercussions on the stomach and the affected person suffers from gastrointestinal discomforts.

No one will now be surprised to learn that enzyme plays a decisive role in the absorption in the building components from the intestinal track to the circulatory system. Furthermore, numerous enzymes are essential as transports for useful substances that the body needs.

You must provide details of the :-

1) Inlet air temperature

2) Fuel characteristic (LHV, sulphur contents, etc.)

3) Site elevation

4) Inlet / Exhaust loss

5) Open cycle type of GT ? Heat Recovery ?

Then the supplier will calculate for you.

Measure the outer diameter of the tube and its' length. Calculate each tube volume and multiply by number of tubes. For those who want to calculate the inside liquid capacity of the shell side, it is advise to include the baffle volume with the tube bundle volume.

It doesn't. Tire rubber (and rubber in general) has vulcanized properties that keep it from melting. The only way you can accuire melted rubber is to have it ordered form somewhere that sells it.

The 2013 AIChE Salary Survey showed that Chemical Engineers have an average starting salary of $67,600/yr (the third highest for any profession) and a median salary for all experience levels of $120,000/yr (USD). Several factors make a difference in these estimates such as geographic region within the U.S., highest degree level earned, gender, age, experience, number of employers, and time with present employer.

The ultimate source of natural sugar based polymers are plants. Plants make sugar (glucose) by photosynthesis. The glucose is then used to make polymers such as starch (amylose and amylopectin) and cellulose. See: http://en.wikipedia.org/wiki/Polysaccharide

Honey is composed mainly of sugar in the form of fructose and glucose. Water, proteins, minerals, and other types of sugars are contained in honey.

The buoyant force on an object submerged in a fluid is caused by the

pressure difference between the top and bottom of the object. To overcome the gravitational force, the buoyant force acts in the upward direction. The larger pressure

at greater depth pushes upward on the object.

The most common ways that sticky notes are used would be to be reminded of appointments, times, dates, or events. Other ways include being used in schools, to help you remember what happened in a book, or also to able certain items or objects.
