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

through explicit imagery and personification of the wind. Petry is able to establish the obstacles of understanding a new place that may seem dark and harsh. . Petry again personifies the wind“fingering its way along the curb” and trying to discourage the people walking along the street” to further show the constant chaos that exists within the Urban setting. In luties attempt to read the sign she in fact fails because the wind is “twisting the sign away from her and holding it at

2.1 How Wind is Created. Wind is defined as air in motion. (1) When wind is being describe you first give the strength of the wind followed by the direction the wind is coming from e.g. extremely windy for a time‚ with strong to gale force and blustery west to northwest winds. (2) Wind is powered by the sun and by the rotation of the planet. Wind from the sun is caused by the uneven heating of the earth by the sun. The equator is heated much more by the sun than the poles. The hotter air expands

Fixed-speed induction generator Many modern wind turbines (especially those manufactured during the 1990s) use a four-pole induction generator‚ which is directly connected to the grid and therefore runs at an almost constant speed: a little over 1500 rpm. A speed-increasing gearbox is used to couple the aerodynamic rotor to the generator. Thus‚ the aerodynamic rotor also runs at an almost constant speed‚ which leads to the term: fixed-speed wind turbine. A very similar arrangement could well be used

Figure (2-3): Schematic Diagram of a Micro-Turbine Advantages: •Micro turbine unit costs around $1500 to $2500 per installed kW. That could lead to niche applications in areas with high-energy costs for power quality‚ peak shaving or replacement energy. They can run on a variety of fuels‚ including natural gas‚ propane‚ and fuel oil. • The other advantages over other types of DG technologies are a small number of moving parts‚ compact size‚ lightweight‚ good efficiencies in co-generation‚ low

Effects of wind-loading on bridges Wind Loading Wind is a word that used to describe the motion of the air. It is the natural phenomenon which caused by temperature differential that is resulted from solar radiation. A moving wind that comes in contact with a solid structure will be distracted. Although the wind structure is not fully stopped‚ it still loses some of its velocity. This is due to the frictional force faced by the wind flow and the surface of the bridge. This phenomenon is actually
