What are some important considerations when designing a wind turbine for your home?
Whether the area that you live in is windy enough to build one. Otherwise you would end up building one to find out that its useless because there is no wind in your area. Basically check that your area has wind potential. Cost is another important factor.
What factors affect the rotation in a DC generators?
Your question is unclear. Do you mean how the rotor of a d.c. generator is driven? If so, then its shaft is connected to a 'prime mover' which can be an internal combustion engine (petrol or diesel engine) or a turbine (steam, water, gas). The type of prime mover usually depends on the source of fuel available to operate that prime mover and whether it is fixed or portable.
What is the cost of wind turbines?
What does it cost to build a wind turbine? Capital costs for wind projects are $1,500 - $2,000 per kilowatt of nameplate capacity. How does the cost of wind energy compare to other energy sources? Wind-generated electricity has become more economical to produce in the past 10 years, dropping from as much as 30 cents per kilowatt-hour to 4.5 to 7.5 cents, making it more competitive with other energy sources. The cost to develop and build a wind energy facility is approximately $1.3 million to $1.7 million per megawatt, compared to a cost for gas-fired energy generation of $800,000 per megawatt.
What is nominal pressure?
Nominal, in this context, refers to the "face value". So in this case it means what the gauge "face" is indicating. Also called gauge pressure. The difference between nominal pressure and actual pressure depends on whether gauge is a calibrated instrument and is indicating the actual pressure.Nominal pressure means rated pressure, that is a nominal pressure rating applied to vehicle parts.Scroll down to related links and look at "Definition of nominal pressure".
How do hydroelectric power stations produce electricity?
Water held high up in the hills behind a dam.Pipework drains the lake to a lower level.The force of the water in the pipe is used to spin a turbine.The turbine is connected to an alternator and produces electricity.When it rains the lake is topped up with water.During low demand periods, water can be pumped back up to the lake as well, using electricty from other sources.
The turbine which rotates in only one direction whether the flow of wind is in either direction what is the name of this turbine?
i have got a pic of such turbine this is designed by some engineering studentshere is the picturehttp://www.engin.umich.edu/dept/name/research/projects/wave_device/picture005.jpg
What is the length of an blade for a gas turbine?
The length of a blade depends on the style (impulse or reaction), the overall size of the turbine, whether it is an axial flow or radial flow turbine, and where the blade is located within turbine of an axial flow turbine. One thing that is constant: the length of the blade increases from the steam or gas inlet to the discharge of the unit. The profile will gradually increase in diameter from inlet to discharge.
How does an water meter works in automatic meter reading?
Whether or not it is a mechanical or electronic meter, the meter is placed along the local water line (the branch off of the main line that carries water to your home, office, store, etc. Water flows through this pipe as you consume it when you turn the taps on and stops when you turn the taps off. A mechanical water meter has a turbine inside that spins as water flows through. This turbine is calibrated to show the amount of water consumed, similar to a speedometer/odometer on a car that shows speed/mileage as the wheels turn. An electronic water meter has a sensor instead of a mechanical turbine that records the flow of water.
Why is there a little spiral on the front of jet engines?
So that it is easier to tell from afar whether the turbine is rotating or not, for safety reasons
Function of Finacial Manager?
A financial manager helps create policies that will safeguard the company's money. The financial manager also analyzes whether a financial procedure is aligned with the business' strategy.
Which direction do the turbines spin in when the tides come in and out?
Turbines typically spin in the same direction regardless of whether tides are coming in or going out. The direction of spin is determined by the design of the turbine blades and the flow of water.
How you increase load electrically in thermal power plants?
Basically you just open the steam turbine steam inlet valves slightly, to admit more steam. The generator is locked to the turbine shaft so will respond by producing more megawatts. Of course the source of the steam has to respond by producing more steam, whether it is a coal or natural gas fired furnace or a nuclear reactor
What changes mechanical energy to electrical energy by rotating a coil of wire through a magnetic field?
That's an electrical generator, whether the mechanical energy comes from steam or water flowing through a turbine, or wind, or tides.
What device changes mechanical energy to electrical by rotating a coil of wire through a magnetic field?
That's an electrical generator, whether the mechanical energy comes from steam or water flowing through a turbine, or wind, or tides.
What are the timing marks for a 1998 Volkswagen Jetta 2.0?
Timing marks are located next to the timing belt. They are the marks that indicate the timing belt is no longer aligned to the engine. they indicate whether or not a timing belt needs replaced.
How many grams a eighth of weed?
1 gram of weed equals 1.0 on a digital scale. Make sure your scale is calibrated properly or it will give an inaccurate reading.
How do you make steam driven turbines?
Most of the parts are created using a combination of casting techniques and precision machining. The tolerances are extremely precise given the very high speeds involved in the rotors and stators. You are essentially making a very large fan. The steam is under pressure and is released into the turbine where it makes the turbine rotate, driving some machine, whether it is a generator or a set of gears to move something.
