The suitable wind speeds are between 7 m/sec and 30 m/sec.
Define Isovents and Isodynes?
Isovents are Contours of constant average wind velocity, in m/s. This data is presented in the form of a wind mop in which the mean annual velocity zones are marked. Whereas Isodynes are the Contours of constant wind power, in watts/m² This data is represented in the form of maps showing the available yearly average wind power.
What is the overall efficiency of the wind machine?
Efficiency of the wind machine varies between 30 to 40%
What is Nacelle?
Nacelle sits at a top of the tower and contains the gear box, low- and high-speed shafts generator, controller, and brake. It is essentially the cover for the machinery that translates wind power into electrical power.
Define power of wind?
The amount of Power of the wind can be obtained from the formula as shown here \(P_a=\frac{1}{2}ρ(\frac{\Pi}{4}D^2)V^3\ Watts\)
Where, \(ρ\) = Density of the Air
A = Traversing area
V = Velocity of air
\(∴Kinetic \ Energy \ of \ the \ wind= \frac{1}{2}mV^2\)
Mass of the Air, m = \(ρ A V\)
D be the diameter of the turbine blades
\(∴A=\frac{\Pi}{4}D^2\ in \ m^2\)
