Atmospheric Issues Anita Curcio SCI / 275 04/27/2013 Maria West Atmospheric Issues "Acid rain" is a broad term referring to a mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors‚ or chemical forerunners‚ of acid rain formation result from both natural sources‚ such as volcanoes and decaying vegetation‚ and man-made sources‚ primarily emissions of sulfur dioxide (SO2) and nitrogen oxides

Lab Instructions: EX: 21-22 Adiabatic Processes: Humidity- the amount of water vapor present in the air. Absolute Humidity- The amount of water vapor present in a unit volume of air. Relative Humidity-the ration of the amount of water vapor actually present in the air to the greatest amount possible at the same temperature. R. H = Actual Water Vapor content/ Water Vapor Capacity (Maximum Capacity that the air can hold) Saturation Mixing Ratio- The water vapor capacity of air at given temperature

To begin the analysis‚ the properties of the air at the base of the tower were examined. The wet and dry bulb temperatures of the air at the inlet were used to find the humidity‚ humid volume‚ and enthalpy of dry air. For example‚ in the first trial the dry bulb temperature was 22.5⁰C and the wet bulb was 16.5⁰C‚ and the properties found from the psychrometric chart are listed below. H_bottom=0.0095 kg/(kg dry air) V_bottom=0.85 m^3/(kg dry air) h_bottom=47 kg/(kg dry air) Then‚ the cross-sectional

Atmospheric issues in today’s society are worse than ever even though precautions have been taken in highly developed countries. While many have taken steps to reduce these issues‚ them and many under developed countries still continue to pour out bad pollutants in the atmosphere. Today I will show you more about ozone depletion and how it relates to indoor air pollution. According to our text ozone "is a naturally produced‚ essential component in the stratosphere‚ which encircles our planet some

Most people do not realize that atmospheric pollution (also known as air pollution) is a very serious global problem. There are a great number of air pollutants that are basically caused from natural resources. Most of the pollutants are mankind. There are seven air pollutants that are at greater risk to our environment‚ which are the following: particulate matter (made up of acids‚ organic chemicals‚ metals‚ soils‚ and dust particles)‚ nitrogen oxides (made by highly reactive gasses that contain

April 6‚ 2013 SCI/275 Atmospheric Issues The atmospheric issue that I chose to discuss was air pollution and the major effects that it has on our environment. The earth is constantly being polluted by all types of gases that are continuously being released into the atmosphere. Not all gases are harmful; actually there are numerous amounts of gases that are released that are needed for humans to survive on this planet. There are a few factors that contribute to pollution more than others which
