ABSTRACT The basic 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

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

“Ode to the West Wind” Theme: - Man and the Natural World Nature itself is more powerful than man but we are part of the natural world therefore man and the natural world is connected. We need to take care of nature as we take care of ourselves for nature is more powerful so then it can strike back to us like the west wind. The west wind represents the period of winter but we know that winter is always followed by spring. Spring symbolizes rebirth‚ life and growth. So we humans

reader. I was sitting in my room when my little sister came in. She had a book in her hand and said that I needed to read it. Well if my sister‚ who barely reads‚ says a book is good‚ then I needed to read it and I’m glad I did. Standing Against The Wind is an incredible book. The main characters‚ Patrice and Monty‚ are an interesting a unique couple. Patrice is a quiet girl who keeps to herself and gets straight A’s in school. She doesn’t have much family besides her mom‚ who’s in jail‚ and her

Inherit The Wind “Truth” VS. What Is “Right” In the play Inherit the Wind the theme of freedom of speech is continuously reffered to. Truth being science and right being the bible both have a crucial battle that contradicts the beliefs of each. Bertram Cates a teacher is denounced by the public as a sinner. Defended by henry Drummond both characters not only defend the teachings of science/truth but the ability to think as well. The repeated contradictions of the towns beliefs‚ continuously

Inherit the Wind is a play about the battle between scientific and religious beliefs‚ and the restrictions upon freedom of thought. The themes presented in Inherit the Wind are timeless‚ and could have taken place a century ago‚ could be taking place today‚ and could take place in twenty years. In order to illustrate the timelessness of the play‚ the country-side surroundings and backgrounds are depicted in a modern setting. This also reinforces the fact that these themes are not obsolete and part

WIND ELECTRICITY GENERATION Introduction Windpower technology dates back many centuries. There are historical claims that wind machines which harness the power of the wind date back beyond the time of the ancient Egyptians. Hero of Alexandria used a simple windmill to power an organ whilst the Babylonian emperor‚ Hammurabi‚ used windmills for an ambitious irrigation project as early as the 17th century BC. The Persians built windmills in the 7th century AD for milling and irrigation and rustic
Free Wind power Wind turbine Renewable energy
Background of the Study A wind turbine is a device that converts kinetic energy from the wind‚ also called wind energy‚ into mechanical energy in a process known as wind power. If the mechanical energy is used to produce electricity‚ the device may be called a wind turbine or wind power plant. If the mechanical energy is used to drive machinery‚ such as for grinding grain or pumping water‚ the device is called a windmill or wind pump. Similarly‚ it may be referred to as a wind charger when used for charging

The Summary of P.B. Shelley’s Ode to the West Wind Published in 1820‚ P.B. Shelley’s Ode to the West Wind‚ is a poem which allegorizes the role of the poet as the voice of change and revolution. Shelley realizes that he cannot in actual life‚ rise to the height of imaginative perfection‚ which was his dream. But it is his bold optimism that he invokes the West Wind to blow the clarion call to the ‘unawaken’d earth’ and to sow the seeds of hope of regeneration. The poem begins with three stanzas

states that plants respire at a faster rate if they are exposed to wind‚ opposed to no wind. This was tested by putting one plant in water in front of a fan and the other plant in water‚ but with no fan. The results showed that the plant in front of the fan transpired more. However‚ since the plant blew cold air it affected the rate of transpiration and altered the experiment. Overall‚ this experiment supports the hypothesis that wind makes plants transpire more.
