ACKNOWLEDGEMENT

With immense pleasure, I am presenting this Seminar report as part of the curriculum of T.E. Mechanical Engineering. I wish to thank all the people who gave me an unending support right from the stage the idea was conceived. We take this opportunity to convey our sincere thanks to our beloved principal Dr.R.V.Kulkarni for his continual support and encouragement that made the Seminar a great success. We express our profound thanks to our respected Head of the Department, Prof. Sunil Ingole whose advice and valuable guidance helped us in making this Seminar interesting and successful one. We are grateful to our internal guide Mr. Chittaranjan More for her support and guidance throughout the course of our Seminar. We also thank all those who have directly or indirectly guided and helped us in preparation of this Seminar. Last but not the least we thank our beloved parents, friends and well wishers who helped us to do this Seminar by their kind help and assistance.
