Energy conservation as it relates to windmills?

Sherri Drakos: law of conservation of power : "power can neither be created , Nor be destroyed , although that is replaced from one variety to a diverse in an same mass" As consistent with the above law the the remainder of the capability of the burnt guy has obtained switched over to another variety i.E warmth capability ( Thermal) and different assets . potential would be unable to be created or destroyed

Von Houskeeper: Do you mean energy conservation, or the conservation of energy?The first wind turbine will extract power from the moving air stream, and since energy is conserved (neither created or destroyed), the downstream air will have less energy. The energy of the moving air mass is proportional to the velocity, therefore velocity (aka air speed) will decrease.The power available from a horizontal axis mill (they look like airplane propellers) is:Power in watts = (1/2) x (air density) x (swept area) x (wind velocity) cubed. Sorry, it isn't easy to type for! mulas in these boxes.air density is 1.23 kg/m3 at sea levelswept are in square meterswind velocity in meters per secondThe theoretical limit to efficiency (called the Betz limit) is 59.26%. Real world generators will extract less energy than this. You could use this for the sake of example, and then work backwards to see how much slower the wind immediately behind the first would be. The energy in front of the mill = the energy extracted by the mill + the energy behind the mill.Have fun with the math....Show more

Ofelia Kieck: I'm guessing it would because the windmill is spinning when the wind hits it so ya i'm guessing it probably does slow it down.
