Kenny Yu EME 1 10/6/08 ENG 103 “Fluid Mechanics” Today, J.J. Chattot, a professor who teaches fluid mechanics, came in and discussed his engineering class to us. He is an aeronautical engineer who has engineered aircraft design, aircraft stability, and aircraft propellers. He has also dealt with energy related projects such as wind turbines. Fluid mechanics is the laws of physics applied to fluid. One of the most important laws as an engineer is the law of conservation of mass. It says that a mass will remain constant despite the action being occurred inside the mass. Having a strong basis by knowing the fundamental theorems is very important in Chattot’s class. During the second half of each quarter, there will be a project worth half the points of a midterm. Some of the projects that are in his class include water rockets, water tower, shock absorbers, bike pumps, water systems, and lifts. After completing a project, they compare

Unformatted text preview: the experiment with the theory. A water tower is very useful when necessary during fires. It stands forty meters above the ground while holding forty hundred thousand gallons of water. It pumps two thousand gallons of water per minute with a pressure of four atmospheres. As an engineer, there are many factors to be aware of like the pressure of the water tower and the stability of the tower in case of an earthquake or flood. Shock absorbers consist of a spring, plunger, and oil. Due to friction from the plunger pushing down on the oil, the motion is slowed down and is absorbed. The energy being pushed down is converted into the oil making it hotter. A bike pump also uses a plunger but instead it is used to push air into bike tires. A valve is at the end of the pump where air doesn’t come out during pumping. The factors that might affect the outcome are zero loss, friction loss, and air loss....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
