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.

Thankyu

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.

Between 150 MPa and 350 MPa, depending on the type.

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.

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
