How big are the wind turbine blades?
Most commercial turbines being assembled onshore in Sweden today (2012) have blades that are about 50 meters long. Offshore turbines have blades up to 70 meters. An 83 meter blade was sent to a testing facility in October of 2012.
How long are wind turbine blades?
The biggest turbines at the moment have blades over 50 metres long. The rotor diameter is then over 100 metres long, longer than a football field. Smaller home, or farm, turbines have blades up to 15 metres (50 feet). The blade length varies depending on output. Typical commercial wind turbines generating around 600kw have blades of 20m. you can find the approximate length of blades for your turbine if you know the required turbine output. L=( P/(Cp*0.5*density*pi*(wind velocity^3)))^0.5 value of Cp < 0.59. usually for good turbines 0.45
Which is faster long bow or short bow?
A short bow is faster
What is downsides of wind energy?
Wind turbines are unsightly;Wind is not steady;Birds and bats are killed striking the blades of turbines;There is a large up-front investment;The return on investment is typically so long that subsidies are necessary to make instalation of turbines financially feasible;Wind turbines are prone to damage from storms.
How long and how thick are wind turbine blades?
Wind turbines blades are about 15 meters long (average wind turbine) The thickness of the blade depends on the length of the blade. The width is about 10% of the length, in this case, would be about 1.5 meters thick.
Which type of scissors would be better suited to cut a piece of metal one with long handles and short blades or one with short handles and long blades?
A pair of scissors with long handles would be ideal, because you can produce more torque when you close your fingers a further distance from the pivot point. In short: long handle, short blade.
Does a long fish swim faster than short fish?
i think that a short one swims faster
What does it cost for large installation of wind turbine?
THE ANSWER IS GOING TO BE EVASIVE. there are blades 50' long and there is blades 10' long. Unless you are specific nobody knows. And the actual cost is hidden usually from state to state because of taxes breaks.
How does wind power help?
Wind turbines use the wind to rotate blades that turn a rotor - which creates electricity. They range from very small turbines supplying energy for battery charging systems (for example on boats or in homes), to turbines grouped on wind farms supplying electricity to the national grid.Wind power helps the environment, because, it lasts for as long as the planet Earth is around. Wind power does not pollute the wind, it can be used almost anywhere it can be hooked up to an electrical outlet, and there are many ways to harness wind power: Offshore, onshore, tall wind turbines (hundreds of feet tall), short wind turbines (tens of feet tall), wind turbines on rooftops, airborne wind turbines and wind turbines that are built by do it yourself people. Wind power does not kill as many bats or birds as anti wind power turbine people claim, and it is not that noisy.
How high are most wind turbines off the ground?
The centers look to be about 150 ft. above ground-level. The blades look to be 30-40 ft. long. Each. Normally 3 blades to the "rig". I've seen several "wind-farms" but can't find a good source for seeds. :)
Which plants' flowers produce seeds faster short-dayplants or long-day plants?
short day plants
Does short cut grass grow faster than long grass?
yes
