concept and operation of subsonic wind tunnel was demonstrated in this experiment by conducting airfoil drag analysis on a NACA 0015 airfoil. The small subsonic wind tunnel along with apparatus such as‚ the manometer rake‚ the inclined manometer and the pitot - static tube were used with different baffle settings to record varying pressure readings. To achieve this objective‚ some assumptions were made for the lower range of subsonic flow to simplify the overall analysis. From the obtained aerodynamic

ODE TO THE WEST WIND Summary The autumnal west wind sweeps along the leaves and "winged seeds." The seeds will remain dormant until spring. The wind is thus a destroyer and a preserver. The west wind also sweeps along storm clouds. It is the death song of the year. With the night that closes the year will come rain‚ lightning‚ and hail; there will be storms in the Mediterranean and the Atlantic. The poet pleads with the west wind to endow him with some of its power‚ for he feels depressed and helpless

| | ADVANTAGES OF WIND POWER: | | | 1. The wind is free and with modern technology it can be captured efficiently. 2. Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants. 3. Although wind turbines can be very tall each takes up only a small plot of land. This means that the land below can still be used. This is especially the case in agricultural areas as farming can still continue. 4. Many people find wind farms an interesting feature

WIND ENERGY Long time ago‚ ancient mariners used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today‚ more and more people are using wind turbines to wring electricity from the breeze. Over the past decade‚ wind turbine use has increased at more than 25 percent a year. Still‚ it only provides a small fraction of the world ’s energy. Therefore‚ wind power or wind energy is the energy extracted from wind using wind turbines to produce electrical

project is a mini windmill that uses wind energy to generate electricity. This process is achieved by creating a propeller and connecting it to a motor. This motor lies on a free rotating base that rotates above a stand (truss) that supports the whole mill. Rotating the base to face the direction of the wind is achieved by connecting a back rudder to the base. • How does it work? Electric energy generation starts when the wind rotates the propeller blades – that have
