Indoor air pollution is defined as the presence of one or more contaminants indoors that carry a certain degree of human health risk. Indoor air pollution dates back to the prehistoric era, where cavemen depicted the problems they encountered with the amount smoke that was present in their cave dwellings. As technology has advanced, to make our lives much more comfortable, over the past several decades there have been a number of products invented or improved. Along with the newer products came new

Atmospheric Issues Morgan Luttrell SCI/275 April 12, 2015 Claudia Listopad, Ph. D. Hello city of Sparksville, I know you are all wondering what is going to be done about the outsourcing of jobs from the area. Without those jobs to help with the economy, the townspeople are suffering. That is why we have decided to look into some opportunities for Sparksville. Those opportunities include bringing a warehouse distributor business, a hybrid car business or an oil refinery to help the citizens

Meteorologist Meteorologists, also known as atmospheric scientists, are experts on the atmosphere, weather, and climate. Meteorologists study the aforementioned categories and how they will affect not only the Earth, but human beings as well. Compiling and collecting data, developing forecasts, and understanding weather patterns are part of a meteorologist’s duties. Furthermore, meteorologists may invent new instruments to collect weather pattern or climate data, while consulting clients on the

feature they will experience is, beyond doubt, the incredible strength of the wind. So How Does a Hurricane Work? Hurricanes begin over warm tropical seas with the movement of a mass of air. The movement of air, wind, is caused by changes in atmospheric pressure as the air warms and cools due to the heating effects of the sun. Warm air is under higher pressure than cold air and so moves towards the ‘space’ occupied by the colder, lower pressure, air. The speed with which the air moves, from a high

Science Project: Air Pressure (Egg in a Bottle) Introduction Atmospheric pressure is the force that acts on any object by the weight of tiny air molecules. Molecules in the air are invisible but they still have weight and they occupy space. Air Pressure changes with the change in the altitude. As the altitude increases the Air Pressure decreases and the altitude decreases Air Pressure increases. At an higher altitudes we have to breathe more often than at the sea level. If you are on Mt Evans then

ROTARY DRYER DESIGN To start the design of rotary dryer design basis for hot air and wet solid feed must be known. Design basis and required parameters are like that: * Feed Temperature (Tsa) = 60 oC * Vaporization Temperature (Tv) = 100 oC * Final Solid Temperature (Tsb) = 80 oC * Wet Bulb Temperature (Tw) = 41 oC * Inlet Air Temperature (Thb) = 150 oC * Relative Humidity of Air: 10 % * Number of Transfer Unit: 1.5 (It can vary between 1.5-2.5) Air outlet temperature

Atmosphere- a blanket of air that surrounds the earth Function of the atmosphere 1. It insulates us so that we don’t freeze at night. 2. Its ozone layer protects us from the sun’s ultraviolet rays. 3. It also contains the carbon dioxide needed by plants for photosynthesis, and the oxygen we need to breathe. Layers of the atmosphere Troposphere • Layer closest to the Earth. • Where all weather occurs • The higher you go in the Troposphere the colder it
