CHAPTER – 1 INTRODUCTION SPEED BREAKER: Perumbavoor is a traffic hectic town where two highways are intersecting. The Aluva Munnar (AM) road and Main Central (MC) road brings in large numbers of cars, trucks and bikes into the town. Even though these roads are very wide enough for multiple lanes of traffic, a free lane system without center lane, dividers, shoulders, stop signs, speed breakers and speed limit signs make the town very vulnerable to accidents and traffic blocks. Traffic deaths of pedestriants from accidents caused by unruly private bus drivers, risky motor bike driving and over speeding is a weekly story. Perumbavoor remains a hot spot for accidental deaths in State of Kerala which itself has the highest accident density for the entire nation. Long voicing by people, businesses and statesmen are showing signs of progress. For example the MC road is being demarked for lanes for independent counterflow traffic. However road AM is still a concern for public especially for safety of school children and minors. India has a huge network of over 3.314 million kilometers of roadways (2.1 million miles), making it one of the largest road networks in the world. This huge network, which includes both paved and unpaved roads, are categorized as expressways or freeways, National Highways, State Highways, major district roads, and rural & other roads. The roads generally are dual carriageways in expressways and highways. Road infrastructure is the main catalyst for the development of important key sectors of economy like Agriculture, Industry, Mining, Energy, Forestry and Dairy Development. These sectors depend heavily on the development and maintenance of the road network and efficient transportation system. 1

CHAPTER -II LITERATURE SURVEY Compressor: A compressor is a machine that takes in air, gas at a certain pressure and delivered the air at a high pressure. Compressor capacity is the actual quantity of air compressed and delivered and the volume expressed is that of the air at intake conditions namely at atmosphere pressure and normal ambient temperature. Clean condition of the suction air is one of the factors, which decides the life of a compressor. Warm and moist suction air will result increased precipitation of condense from the compressed air. COMPRESSOR MAY BE CLASSIFIED IN TWO GENERAL TYPES. 1. Positive displacement compressor 2. Turbo compressor Positive displacement compressors are most frequently employed for Compressed air plant and have proved highly successful and supply air for pneumatic control application. THE TYPES OF POSITIVE COMPRESSOR 1. Reciprocating type compressor 2. Rotary type compressor Turbo compressors are employed where large of air required at low discharge pressures. They cannot attain pressure necessary for pneumatic control application unless built in multistage designs and are seldom encountered in pneumatic service.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
