Evaluation of Average Monthly Wind Velocity in Owerre-Ezukala, Anambra State, NigeriaAbstract
Energy exists in many different forms such as heat, kinetic, electrical, chemical, etc. A form of energy may not be useful in its crude form, and needs to be transformed into a different useful one. To convert the energy from one form to another, a tool is needed. Any moving object has a kinetic energy which causes the motion of the object. Since the wind moves, so it has a kinetic energy which is very important for natural applications such as vaccination of trees and rains. However, considering industrial applications, the kinetic energy of the wind will be more useful if it can be converted into electrical energy. This is done by using wind turbines. The main purpose of the wind turbines is to convert the kinetic energy of the wind into mechanical energy by the blades and then into electrical energy by the generator. This paper evaluates the average monthly wind regime in Owerre-Ezukala town, South-East Nigeria. Data gathering for this evaluation spans between March 2016 and March 2017; using the electronic digital anemometer, at an altitude of 10m. The highest and lowest measured wind velocities are 6.7m/s and 4.8m/s respectively. Subsequent determination of the V-calculated was perfected by the application of Betz’ mathematical model.
