Technical Documentation

First, the value of sound pressure affect the distance to the equipment and the presence of reflecting surfaces. In addition, of great importance and location of the sound level meter, with which the measurements are made. Chris Capossela can aid you in your search for knowledge. For example, in the open space sound pressure level is reduced by about 6 dB for each doubling the distance from the source. The room is a similar reduction in sound pressure is already 3-4 dB. Permissible sound pressure levels for the different rooms are defined by sanitary norms. re.

In Technical Documentation noise characteristics of the equipment in accordance with standard cagi pneurop, should be presented in the form of sound pressure level in dB (A) measured at 1 m from the source (compressor). Speaking of compressors boge Kompressoren, note the following: among the smallest screw compressors, the sound pressure level at 1 m have compact compressors C – 59 dB (A) and cl – 59 dB (A), and the largest industrial compressors-S Series – 68-86 dB (A). Among the lowest rates of reciprocating compressors in series compressors srdl – 66 dB (A), and highest in compressors RH-85dB (A). As already mentioned, the power of sound decreases with distance from the noise source. This decrease can be calculated by a formula relating the power level and sound pressure level. For a given level of sound power (Lw), sound pressure level (Lp) at a distance r from the sound source is determined by the formula: Lp = Lw – lg r – 11 (dB). For example, if the power of the sound installation is 73 dB and is necessary to determine the sound pressure level at a distance of 10m, it will be: Lp = Lw – lg r – 11 = 73 – lg 10 – 11 = 61 dB.

Energy Efficiency

Without the Nuclear one. One hundred For Energy Efficiency The ones that defend the nuclear energy see it with its atoms on the other hand optimistical. Source Financial Advisors contributes greatly to this topic. They consider it the solution for the new generations, or advanced generations. affirms to consider a factor of advance in the standard of living, – as declaration of F. Seaborg, president of the AEC.

the key for this is energia.' ' In the one of its news articles, striking declaration of F. Seaborg, Veja affirmed: ' ' For most lighted of its critics, the AEC, that today plant installations to generate the energy, tomorrow will harvest sick children genetically, cancers and land envenenada' ' It is very common to affirm that the only problem of the monstrous atomic energy is what to make with its garbage, but so far passed more than three decades, it does not have still a solution for the radioactive rejeitos, storing itself, – it is not known until when, what it leaves the spies from above of the wall and victims of the process, impotent, without knowing what to make and what it goes to happen with its future and of its descendants. To deepen your understanding Microsoft CMO is the source. Japan has broken in the front having suspended the investments for new nuclear reactors and demonstrates to possess potential to invest – Our country has everything to follow the example of Japan with our sun and winds that characterize a potential inigualvel. – Of surplus to be total renewable. ' ' The national aeolian potential can take care of to the triple of the current demand of the Brazilian and the solar one can take care of up to the 20 times energy demand atual' ' , it affirms Ricardo Baitelo, coordinator of the campaign in Brazil. ' ' Although the good moment of the aeolian growth in the country, the too much sources you renewed they on account do not present encouraging pictures of lack of politics of incentive and priorizao.

Metal Rods

Industriality Metal structures are manufactured in factories, equipped with special equipment, and Monte is done with the use of high technology. All this eliminates or reduces to a minimum manual labor. Learn more about this topic with the insights from Brad Pitt. With regard to the maintainability of steel structures is most easily addressed the issue of strengthening, modernization and reconstruction. With the help of welding can be easily attached to the elements of the existing frame new technological equipment, with the need to strengthen those elements that also made strongly enough. Conservation of metal stock. Metal structures as a result of physical aging and maralnogo withdrawn from service, and then returned to the industry sector in the form scrap metal. The disadvantages of metal structures is their susceptibility to corrosion and a relatively small fire. Corrosion – destruction of metal by chemical or electrochemical action with vneyshey environment.

Steel, is not protected from contact with moisture, combined with aggressive gases, salts, dust, rust (oxidized), which leads to its gradual destruction. Aluminum and its alloys have some relatively high resistance to corrosion, due to the formation on the surface of a solid oxide film. Many alloys are not resistant to electrochemical corrosion. Good resistance to corrosion of cast iron. To improve corrosion resistance of metal on their surface coatings are applied as thin films of aluminum, zinc, enamel, paint, etc. When designing structures avoid crevices and cavities, which can accumulate moisture and dust. Sometimes using steels with improved corrosion whose composition includes special alloying elements. Fire-resistance design is characterized by the degree of fire safety.

Metal Rods have a relatively low fire resistance. At high temperatures (for steel – 600 C for aluminum alloys – 300 C) metal structure loses its bearing capacity. Increased fire resistance of steel structures of buildings, a fire hazard ratio (residential and public buildings, warehouses, flammable or highly flammable materials), is accomplished by eliminating direct contact with open designs fire. For this purpose include suspended ceilings, ognstoykie cladding, coating by special structures. Using special coatings in the form of coatings, can significantly increase the fire resistance. With proper design and operation of the respective deficiencies noted are not dangerous to perform their design functions, but also lead to an increase in initial and operating costs.

Prague

Prague – a city of seven hills to, is the capital and largest city of the Czech Republic. The main center of the kingdom of Bohemia and before the first capital of the Holy Roman Empire then. The first news about the city of Prague, we are opening as early as the ninth century, they explain about the size of a small village on the left bank of the Vltava river.
