What chracterizes the axial flow turbine is its rotation axis. It could be placed vertically or horizontally to water surface. In this latter type the axis is parallel positioned to the incoming water stream. Also the generator can be submerged under water or non-submerged. This turbine is usually used as tidal energy converter. For small river use, the axis could be an angle inclined to the water stream. See figure \ref{Hydro_HorizontalAxis}. Hydrokinetic converters with a vertical axis…

The experiment of fluidization in packed column was determined by using air as the conveying media. The fluidized bed is when the air make the solid to behave like a fluid. For this experiment, two columns are use which one column are filled with sand and the other one filled with aluminum oxide. The bed height of aluminum oxide is 100 mm and have a particle size about 250 micron (mesh 60). The minimum fluidization velocity is used to determine the pressure drop. As mentioned above, when the…

According Peter M. McGinnis (2013) the Newton’s first law is about the linear kinematic and is called law of Inertia. This law states that, ‘everybody continues in it states of rest, or of uniform motion in a straight line, unless is compelled to change that state by forces impressed upon it’ (McGinnis, 2013, p.88). Simpler, the law of Inertia says that if there is no external force acts on a subject, that subject will not move and it will remain in states of rest or if it was moving it will…

INTRODUCTION Can the magnitude of gravity be found by measuring the period in relation to the length of the string of an oscillating pendulum? The aim with this lab was for us to gain a greater understanding in the area of oscillations and simple harmonic motion. Also to determine if the use of a pendulum is a good strategy for measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they…

WERNHER VON BRAUN Wernher Magnus Maximilian Freiherr von Braun, the father of modern rocketry and one of the most important outer space engineers of the 20th century, was born on 23th of March 1912 in Wirsitz (Wyrzysk)(today in Poland). He was a child of a wealthy family from Germany. With their second son, Wernher, Magnus von Braun and Emmy von Quistorp moved to Berlin in 1915. In those years, Wernher von Braun became interested in music and astronomy. And his passion, astronomy, went on for…

Investigation Hooke’s Law AIM: To investigate how a spring behaves when a force of load stretches it. To figure out the relationship between the loads added to spring and the extension of spring. HYPOTHESIS: I think that as the load added to spring increases, the extension of the spring will increase. The relationship between them will be directly proportional. The formula of these two variables might be F=kx. F stands for the load added to spring, k is spring constant and x stands for…

Omar Alawad Math SL Mr. Sidat Stopping distance Introduction When driving on roads, drivers may see an obstacle ahead that requires them to apply brakes suddenly to stop. The distance covered by the car from the moment the driver applied brakes to the moment the car stops is called the stopping distance, which is also referred to as the braking distance. For a car travelling at an initial speed of , the stopping distance traveled by this car is given in the formula: The stopping…

In our lab, we had to do experiments to answer the following questions: Problems: Is the frictional force greater when an object is still (static) or sliding? 2) Does the surface area of contact between two surfaces affect the frictional force? 3) Does the type of surface (carpet vs. hard/smooth surface) affect sliding friction? 4) Does the force between two objects (weight) affect sliding friction? While doing this lab, we were able to answer the given questions and we were…

I Anatomy of the shoulder The shoulder joint, as it is commonly called, is not a single joint but a complex arrangement of bones, ligaments and musculotendinous units that called the shoulder girdle. The primary role of the shoulder girdle is to provide a tremendous range of motion for positioning the upper extremity in space. The shoulder girdle also provides power and support for the upper extremity throughout and at the extremes of the range of motion. (19) The…

I argue that many different branches of science are reducible to one fundamental one- physics. In this essay, I will use Pasteur’s work to demonstrate that biology and chemistry are reducible to physics - the study of interactions between matter and energy. By reducible, I mean that these sciences (and other hard sciences) can be simplified to the point where they deal with the same fundamental matters as physics. During the 1700s, chemists engaged in a long-standing debate over what caused…
