Proposed Ban of Ozone-Depleting Aerosol Spray Fact and Opinion Speech Review Suzie Student Course ENG101 June 25‚ 2010 Matt Copeland The speech‚ “Proposed Ban of Ozone-Depleting Aerosol Spray‚” describes a five-month study that was conducted in 1974 by a special administration task force made up of a group of scientific researchers who concerned themselves with the dispersion of fluorocarbons. These fluorocarbons were found in most aerosol cans‚ air conditioners‚ refrigerators

Assignment – Ozone Debate The debate over whether or not the ozone is actually depleting or not has been a hot topic for some time. However‚ it becomes a hotter topic when scientists find out it is a lower level then usual. We don’t here much from the debate when it has replenished itself to some amount‚ which it does do during certain seasons. Between the two sides we are to take‚ I am basically right in the middle. I do believe what the NASA website stated about it when it said “the ozone is extremely

BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1.

ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.

But there is a significant pending problem in the ozone layer. Each year‚ a large hole appears in it. It is not an actual hole‚ like a hole in a pocket‚ but a thinning in the layer that shows up on satellite pictures. The "hole" is located over Antarctica. It covers an area about the size of the United States. Experiments done in Antarctica show that the hole in the ozone layer appears to let in twice as much ultraviolet radiation as normal‚ according to measurements researchers made there only
