Calculations of the Jet Propulsion

Burning of a rocket propellant of a spacecraft is the best way to produce a net change of speed in space, New York we call this variation the 'delta-v'. The variations represent the total velocity as the 'v of a vehicle and one of the uncertainties when used to solve the equation of a rocket cinematics, where M is the mass of fuel (or propellant), P is the mass of the load (including the mass of the rocket estrucural) and see is the speed of evacuation of propellant to the nozzle. All these parameters are part of Tsiolkovsky's equation:
For historical reasons, the speed is often written as
where Isp is green energy the specific impulse of the rocket, measured in seconds, and g is the gravitational acceleration at Earth's surface. To travel long distances most of the mass of the spacecraft mass is reactive. Because it is necessary that the reactive mass provide a speed increase to the mass of the payload. If you have to provide a payload of mass P of utilities a change of speed 'v, and the rocket motor has a speed of evacuation is then the reactive mass M would be calculated by using equation Tsiolkovsky Isp
For 'smaller than the v see, this equation is linear and can be seen that simply use a small mass reactive. If 'v is comparable to being, then there New York State is the need to gas need about twice that mass propelante payload (which includes engines, fuel tanks, structure, and so on). After these features is exponential growth with speeds higher than the speed of evacuation require very high ratios of mass propelante with respect to the payload (payload). To achieve this, any amount of energy must be able to accelerate the mass reactive. It should never assume that the environment engines (by thermodynamic rules) are 100 efficient, releasing energy without using, but assuming a 100 efficiency would require an energy of
Comparing with the rocket equation (which ESCOs shows how much energy you need a car) and the energy equation (which shows the total energy required) can be checked under the assumption that energy service company 100 efficiency in the engine, not just all the energy provided in the vehicle - if some of it, in fact most of it ends natural gas up being the kinetic energy of mass evacuated. For a mission, for NY example, launch and planetizaje (landed on another planet) is necessary to take into account that we must overcome the forces of gravity (they are resistant to take-off and cause an increase propelnte necessary). It is typical to consider these and many other caractersisticas to achieve a correctdelta-v impact on the mission. For example, when a ship is launched on a mission to orbit requires a low delta-v of 9.3-10 km / s, this value is part of the integrated number of computers on board.
For example, if you want to send 10,000 kg to Mars. The 'v required to reach a low orbit (igl. join the energy savings revolution, by getting the best prices for your electricity and gas from Low Earth Orbit or LEO) is approximately 3000 m / s, using a Hohmann transfer orbit. If there need to steer the ship will need much more propelante. To adjust the argument, the rocket boosters used today are:
It should be noted that when it is more efficient in fuel consumption engines may need less electricity weight propelante for the same functions, this mass is almost negligible (relative to the payload mass) for some of the engines. However, New York City it is noteworthy that required a large amount of energy.

Hazards

Physical
The gas is lighter than air. energy costs The gas mixes well with air, explosive mixtures easily.
Chemicals
The intense heat may cause violent combustion or explosion. Reacts violently with air, green energy oxygen, chlorine, fluorine and strong oxidants causing fire and explosion hazard. Metal catalysts such as platinum or nickel increases this type of reactions.
Fires
Avoid flame, no spark and no smoking. Extremely flammable. Its flammability range is very large. Many reactions may energy cause fire or explosion. If possible, cut off the supply. If you can, and no risk to the immediate environment, let the fire extinguish itself. Extinguish with water household spray, dust, carbon dioxide and halons. The hydrogen is producedwhen fire heating or explosion burns with an almost invisible flame.
Explosion
Mixes gas and air are explosive. Prevencion as it should be adequate ventilation. Hand tools should not generate sparks. The electrical equipment and lighting must be prepared to test explosion. The electricity ESCO fire must be fought from a protected location.
Spills and leaks
To check for leakage, using soap and water. Evacuate danger area. natural gas Ventilate enclosed areas to prevent formation of flammable atmospheres or oxygen deficiency. The vent can be manually or mechanically. Remove all potential sources of ignition. For additional help, consult an expert. Wear self-contained breathing apparatus.
Exposicion
Hydrogen is not toxic and is classified as a simple asphyxiant. The amount needed to reduce the concentrations of oxygen at a lower level than required to support life cooking gas cause mixing within gas the ranges of flammability. Therefore, prohibiting entry into areas containing flammable mixtures because of the immediate danger of fire or explosion. The hydrogen can be absorbed by inhalation and through the skin.
To cause loss in confined areas, this liquid evaporates very quickly causing a total saturation of the air can cause choking, difficulty breathing, and unconsciousness. Prevencion as it should be adequate ventilation by introducing clean air.
Contact with liquid is freezing. As prevention is to use cold gas insulating gloves and protective clothing.

Positive socio-economic impacts of this industry are obvious: fertilizers are critical to achieve the necessary level of agricultural production to feed the world population growing quickly. In addition, there are indirect positive impacts on the environment from the natural use of these substances, such as chemical fertilizers allow intensify existing agriculture land, reducing the need to expand it to other land uses that may have natural or social different.
However, the negative environmental impacts of the production of fertilizers can be severe. Sewage is a major problem. the improvements that have been afforded the general household by all through the State of New York Can be very acidic or alkaline and, depending on the type of natural gas plant, may contain substances toxic to aquatic organisms, if the concentrations are high, ammonia or ammonium compounds, urea nitrogen in plants, cadmium, arsenic and phosphorus the operations of phosphate, if present as an impurity in phosphate rock. It is also commonly found in the effluents, total suspended solids, nitrate and organic nitrogen, phosphorus, potassium, and (as a result), a lot electricity ESCO of biochemical oxygen demand (DOB5) and, with the exception of biochemical oxygen demand, these contaminants occur also in the storm water runoff from areas that material storage and waste. You can design phosphate plants so that there is no discharge of sewage, except for the overflow of a pool of evaporation during the season of excessive energy rain, but this is not always practical.
Fertilizer finished products are also possible contaminants in the water, excessive and inappropriate use can contribute to eutrophication of surface water or contamination of groundwater with nitrogen. Furthermore, the exploitation of phosphate may cause negative effects. the energy market has been greatly improved by an energy supplier These must be taken into account when predicting the potential impacts of projects that include the gas operations of new or expanded extraction, whether the plant is located near the mine or not (see the section "Mining and Mineral Processing) .
Particulate air pollution from boilers, phosphate rock crushers, phosphorus (the main atmospheric pollutants that originate in plants phosphate), acid mist, ammonia, and oxides of sulfur and nitrogen. Solid wastes are produced mainly in the phosphate plant, and ash are usually (if coal is used to produce steam for the process), and gypsum (which may be considered dangerous because they contain cadmium, uranium, radon gas and other toxic elements of rock phosphate).
The making and management of sulfuric and nitric acid is a risk and danger to health, very big. Accidents producing ammonia leak could endanger not only the workers of the plant, but also the people who live or work in places nearby. Other explosions were household accidents and injuries of eyes, nose, throat and lungs.
As some of the impacts that have been mentioned can be avoided completely, or attenuated more successful at lower cost, if the site is chosen with care. (see, with this chapter: "Plant Location and Development of Industrial Parks"

The country is regarded as one of the 17 countries Megadiverse for having a large number and diversity of species, especially in regard to plant species and birds. And the climatic diversity and at the same time, the stability of the elements of climate, have made many plant and animal species from other parts of the world have been entered and found a very suitable habitat for development and nearly all crops domesticated species can be cultivated by man in Venezuela on very favorable terms, a fact already recognized the nearly two centuries ago by Andres Bello Silva in the agriculture of the torrid zone. Venezuela is composed of three strands hidrograficas the Caribbean Sea, the Atlantic Ocean and the Lake of Valencia, which is an endorheic basin. The main one is the Caribbean by the number of rivers that form, although usually short-course and flow of small and irregular, with some exceptions such as Catatumbo, who was born in Colombia and drains into the Lake of Maracaibo. Andalusia Oceano Atlantico drain the extensive Orinoco River, which is above the surface of all Venezuela. The Orinoco basin is the third in South America for its surface and gives rise to a flow of around 33,000 m per second, making one of the Orinoco rivers flowing into the world and also one of the most valuable in terms of renewable natural resources. A river is a unique event in the world is the Casiquiare, which is a derivation of the Orinoco and natural that, after about 500 km long, flows into the Black River tributary which is in turn the Amazon.
The main tributaries are the Venezuelan Orinoco and Apure Arauca by the left and Ventuari, the Caroni and Caura by the right, among others.
