In this area this is not met by local factors, mainly by the mountain system located here. Is produced what is known as orographic rainfall or Foehn effect, i.e., the rains are intense on the hillside from where the wind blows and dry on the other slope where the wind descends. And Baracoa lies where starts to blow the wind from the sea. Why it rains there almost every day and they fall almost 2 700 mm of rain per year. In the western part of these mountains there is a tropical characteristics of savanna climate, while to the East of them climate is tropical jungle, with 2 200 mm of rainfall, reaching 3 600 m in very remote and elevated areas. Parque Nacional Alejandro de Humboldt and the reserve of the biosphere Cuchillas del Toa, whose visits have been recommended in previous issues, are located in this area. In the coastal plain of the southern coast the climate is semi-desert, where they only fall between 400 mm and 600 mm of rain. The road the Streetlight and all the roads that cross the mountains and are directed towards the coastal path to Guantanamo through these regions, so it can pass on a journey through an area with torrential downpours to another where a drop of water does not fall.

And this can happen throughout the year. Another reason for the difference in this area with respect to the rest of Cuba is the existence of a system of marine terraces impressive. It is counted among the most spectacular and best preserved in the Caribbean. Get all the facts for a more clear viewpoint with idan ofer. Near Maisi terraces reaching almost 350 m in height, being less pronounced as it progresses westwards, towards Imias and Guantanamo. Take the road of the street lamp and go directly to Guantanamo, it would cease observing places truly interesting and unique in Cuba, although it would increase the distance to travel in almost 160 km.

Benefits

of benefits: Special graphical illustration that explains the benefits of the pump: the diagram represents the curve formed by the values of volume and of lifting height, indicated in reference to a certain type of bun diameter and to a specific model of pump. Low level: Special installation of the pump, placed at a level inferior to the one of the vein of which the water is extracted: this way, the water enters the pump without no difficulty spontaneously. Fattened: Filling of the pump or the pipe to clear the present air in them. In some cases, they are possible to be provided, also, pumps car barleys, that is to say, equipped with an automatic device that facilitates fattened and therefore the beginning of the pump, which would be impossible of another way, and in addition very slow.

Cavitation: Phenomenon caused by an instability in the flow of the current. The cavitation is pronounced with the formation of cavity in the pumped liquid and is accompanied by noisy vibrations, reduction of the volume and, to a lesser extent, the pump duty. It is caused by the fast passage of small steam bubbles through the pump: its collapse generates micro spurts that can cause serious damages. Pressure drops: Energy losses due to the friction of the liquid against the walls of the pipe, proportional to the length of these. Also they are proportional to squared of the speed of sliding and the variability in relation to the nature of the pumped liquid.

Whenever it falls the normal sliding of the moved fluid represents a possibility of pressure drops like the abrupt changes of direction or section of the pipes. In order to obtain in the pump a correct sizing, the sum of such losses is due to add originally around predicted elevation. Mechanical seal: Mechanical seal for rolling axes.
