How many watts does an eighty foot tall wind turbine produce?
The height of a wind turbine has no impact on the turbine's output wattage. The factors that effect the watts produced are: * The efficiency of turbine design (this is at most 59%) * the density of the air * the radius of the turbine (that is, the length of each fin) * the velocity of the wind passing through the turbine An 80 ft tall turbine would presumably have a fin length (that is, turbine radius) of at most 30 ft. Thus, at sea level on a 59 degree (F) day, in an 8 m/s (18mi/h) wind, with the most efficient turbine design possible, you would generate approximately 15.4 Kilowatts.

What relationship exsists between turbine and generator?
A turbine is powered by such things as steam, burning gas or oil, water, or wind. The turbine is a type of engine, which might be thought of as a more efficient choice than a gas engine or reciprocating steam engine for doing the same job. The turbine could do many things ranging from powering a vehicle such as a helicopter, a ship, a locomotive, or a piece of equipment such as a centrifuge, a pump, or a generator. When a turbine powers a generator, the generator makes electricity.
How many people does it take to build a wind turbines?
It takes about over 500 people to build a turbine wowza!
Why mostly steam is used to rotate a turbine?
The Rankine cycle is one where a closed loop containing water/steam is used to transfer energy from an energy source such as a coal fired furnace or a nuclear reactor to a steam turbine/generator. It is the way all such power plants work, but not plants using gas turbines or combustion turbines which don't use a water/steam circuit. In the Rankine cycle there are progressive stages: 1. Cool feedwater is pumped at high pressure into a boiler which is heated by the furnace or nuclear reactor 2. The water is heated and evaporated at high pressure, becoming steam 3. The steam is further heated to become superheated 4. The steam is admitted to the HP end of the steam turbine, and it progresses in stages to the LP end by which time it is cooled and under vacuum (the vacuum is maintained by external cooling water and increases the efficiency considerably by getting the maximum energy out of the steam) 5. The steam condenses in the turbine condenser under vacuum, to produce cool water, and hence back to stage 1. Electrical energy is extracted by the generator which is coupled to the shaft of the turbine, but that is not really part of the Rankine cycle, which is described in thermodynamic terms only. See link below for more reading and diagrams.
Where can I find information about how to build a gas turbine for a science fair project?
Truthfully a gas turbine isn't all that practical because of the danger of a serious mishap and the expensiveness of the complicated machine parts you'd need. A better option would be a steam turbine, which is the same concept, but not quite as complex or dangerous to play around with. You can go to http://www.scienceproject.com/projects/index/elementary.asp for information on this sort of project and many other ideas. There are a number of websites that detail the construction of a gas turbine. Safety is an issue and the project should be managed by an adult at all times. Check out the information at these sites: hhttp://www.aardvark.co.nz/pjet/faq.htm AND www.junkyardjet.com/ AND freespace.virgin.net/dyno.power/gasturbine This article discusses how the turbine works: www.gp3.co.uk/Build.htm AND There is a website that explains how to build a gas turbine in detail. The website is: http://www.gp3.co.uk/Build.htm.

How many mho in simens?
First of all, the correct spelling is 'siemens' (symbol: S), which is the SI unit of measurement for conductance -the reciprocal of resistance. The mho is simply an obsolete unit for conductance, and is exactly equivalent to the siemens.
What is the compounding steam turbine?
Velosity compounding:This is a combination of pressure-velocity compounding. Lets say you have superheated steam coming out of the boiler at 70 bar, which is suppose to drive a steam turbine. How many stages of blading required to reduce the pressure to acceptable exhaust pressure so that it does not overheat the condenser?Remember, when you reduce the pressure the kinetic energy increases so is the steam speed. In order to reduce the pessure you must have pressure compounded arrangement. In order to reduce speed you must have velocity compounded. So what is pressure componded?This is an array of nozzles and impulse blades laid out accordingly to mainly reduce the steam pressure as it pass through the respected stages.Notice the pressure drop gradually as it pass through a fixed blade stage, but the speed increases as it pass the same stage. The velocity compounded which is arranged so that you have nozzles,moving and fixed blades laid accordingly. As it enters the nozzle the pressure is dropped, steam velocity inctreased.Then it pass through moving blades which reduces the steam velocity but maintain steam pressure.Then the steam is pass through guide blades or fixed blades where further reduction in velocity but none in pressure.Last stage is moving blades where velocity is reduced but pressure is maintained. How is pressure-velocity compounding accomplished? Answers: It is a combination of pressure compounding and velocity compounding. Steam is expanded partially in a row of nozzles whereupon its velocity gets increased. This high velocity steam then enters a few rows of velocity compounding whereupon its velocity gets successively reduced. The velocity of the steam is again increased in the subsequent row of nozzles and then again it is allowed to pass onto another set of velocity compounding that brings about a stage-wise reduction of velocity of the steam. This system is continued.
