The Geometric

Posted by admin on

When his unit dug pit at the bottom of which there is a bias toward the center. Then, on the gravel drainage network training fit – drainage pipeline for untreated sewage. Next comes the filter layer greater than in the case of fields of filtration thickness. It can reach 1.5-1.8 m. Then he laid crushed stone or gravel, and on it – irrigation tube. The performance of this system is about 100 liters / day. meter on the irrigation pipeline.

The filter trench – a more modest post-treatment facility capacity. They have almost the same device, sand and gravel filter. The main difference is that the irrigation pipes are located is not a network, and linear, each in his own trench. Companies that are developing such systems offer different options material loading and the geometric dimensions of the trenches. An example of construction using the cleansing properties of the soil, may serve as a filtration plant type (septic system and biofilter). These settings are designed at different volume flows from 750 to 4000 l / day. Their work is based on the mechanisms of ground clearance. First, liquid wastes enter the septic tank, made from high quality fiberglass.

Then, waste water, freed from suspended particles and impurities are sent to a distribution well. From there, they served in the spray tube and are dispersed over a layer of crushed stone preparation. In the crushed stone and sand layers of the soil filter is an aerobic post-treatment. Question discharge treated sewage is solved individually for each case.

Design Of Overhead Power Lines And Equipment

Posted by admin on

When designing the main power grid power is recommended: to chart the power line through the major assemblies of the load, to avoid direct links between power plants, produce selection scheme accession power plant and substation to the main network, taking into account the reliability of power supply node electrical network and the need to provide transit facilities for overhead lines; construct between two network nodes on one route, usually no more than two lines transmission of one strain. If necessary, additional strengthening of the network should be considered the feasibility of construction of the il other areas, or performing power at a higher voltage. Design of power distribution network by taking into account: in areas with low coverage of the networks with similar values of technical and economic indices of development options for the network encouraged to give preference to the construction of overhead lines on new routes and in major cities and industrial areas with a large concentrated load on one path may provide the construction of two or more overhead, with passing overhead on the territories of cities, industrial areas, the approaches to power plants and substation. in cramped conditions, in forests, etc. il recommend that you perform on the double circuit towers. In this case, suspension of one chain recommended when the need to enter the second strand occurs in more than three years after entering the first, and when disabling the first circuit at the time of suspension of work on the second allowed by the conditions electricity.

Yes Lacoste

The French school is only born when France is defeated by Germany in the war in 1870, French geography in turn, keeps a imperialista model of German geography, however German geography if it supported in the kantiano idealismo, as Humboldt if they differentiated in the reference scale, Humboldt was total totalizante and regional Ritter therefore, geography that we today have in our schools and university, is geography for them systemize. The strategists of the war of the Vietnam, had been the geopolitical ones, however she is possible to affirm that geography came if becoming one sets needs control d and space, Yes Lacoste affirms that _ geography more serves before nothing pra to make the war. The fight that if had in the decade of 70 of the socialism and the democracy, comes of the combination of the crisis of the capitalism, resulting in the desistalinizao of the composition of the world-wide politics. Pierre George was the responsible one for the loss of the natural division of the continents, therefore the world finishes for if to divide in two systems, the capitalist and the socialist one, geography if includes in the countries, depending on the organization of its economic system. The development in the formation of the geographic thought if makes necessary, from the moment where the man if makes use to want if for the one along with the beddings and of the structure of the same one. Pestalozzi affirmed that geography was better understood when to the one contact of interaction with the exterior world, it privileged the nature to have one better resource of learning. With the mercantilizao of the merchandises, the capitalism has force enough to become enlarged itself of form that its subsistence was guaranteed for the nature, all this process alone showed that if it could affirm that as much the man and the capital, more early or later would enter and contradiction with the nature. It is the work that establishes the man the nature and it demarcates at the same time them, therefore the man is the only being, that if reproduces conscientiously; the work processes if modernize and with this to an accumulation in the space, example of this is verticalizao of the cities, with this the dispute of classrooms is present constantly. Geography therefore, is a measure for the improvement and good of all, only depends on the men make who it they use that it of a correct form to reorganize spaces, to explore places, and to expand its knowledge on the same one.
