How many blades does a windmill have?
four
How big were the blades on the first windmill and how many blades are there?
130 feet long and 4 blades
How many blades do you need for a windmill?
Answer: I googled this question and the answer is: 3. Commonly. Not always, but 3 is the amount you mostly see.
How does wind power generate electricity?
Wind energy (Kinetic) is transformed into electrical energy (Potential) with the use of a turbine-generator. The wind turns the blades of a wind turbine. These blades then turn a generator, something which uses magnets (specifically magnetic flux) to create electrical energy. As electrical energy is a form of Potential energy, the energy has been converted from Kinetic energy (the turning of the blades) into Potential energy (also known as "voltage") by the generator.More detailsA generator is a coil of wire surrounded by magnets. When the coil spins or the magnets spin, electricity is created. You need something to cause it to spin. In your car the gas engine does. At a hydro-electric dam, falling water that drives the turbines' blades. At a coal-fired power plant, expanding steam drives the turbines which in turn drive the generators. And in a wind generator, the wind turning the propeller blades drive the generator.A wind generator makes electricity just like any generator: the fan blades drive a turbine which turns the generator. The amount of power (wattage) produced depends on several things including the speed of the wind, the size of the propeller blades and the size of the generator.It is the same process, just a different power source.A wind turbine - as any turbine, is an energy converter. It converts wind energy into mechanical energy and then electrical energy. Some so-called direct-drive turbines use magnets to keep it running even when there's no wind. Now direct-drive turbines are used. The number of blades do not matter (too many blades = too much turbulence), The span of the blades make more power. That's the smarter way to make more power. In 1985 blades had a span of 30 ft. Now they get to over 200 ft.
How many rotations does a windmill make per minute?
It depends on the wind and the rating for the windmill
How many blades does a windmill have?
four
How many blades should i put on my model wind turbine?
The number of blades in wind turbine is not determined by aesthetics but by science. The size, shape, solidarity, and positioning is determined by the weather conditions and power output. Current tubbiness include turbines using vortexes (no blades) and high solidarity turbines (12 blades) once popular on farms to pump water.If the model is a replica of actual turbine the number of blades in the model will be the same as the number in the actual unit.

How many blades do most wind turbines have?
There are 3 blades3 blades on each turbine
How many stages of steam turbine rotor?
It depends upon megawatt of turbine & design of blades.
What are the part of the windmill?
The simplest part of a windmill are the rotor blades, generator and the shaft. but there are many parts when it comes to wind turbines. hope this helps!

How many feet wide is a wind turbine?
Wind turbine vary enormously in size from a small turbine on a boat with blades about two feet in diameter to large industrial 'wind farms' the blades of which are individually dozens of feet long

Need 2kW power out of wind turbine how much is the diameter of the blades with .25 percent stream factor and average wind speed is 12mph?
3 piece blades ,the diameter of the blades is 2.0m . We are a professional manufacturer of wind turbine ,and we have many specialist , we are pleased to talk with you . Allan@minjia.biz Skype : minjia002
How many windmill are present in India?
unknown number.
Why there is no use of saltwater to produce electricity?
in hydroelectric generation system.you use a turbine which have many blades like wings,water comes from the nozzels to the blades and blades are made by an mettalic material,if you use the salted water there will be more rusting.
