Have you ever wondered how trajectory and the pressure in the atmosphere affects the spin of a soccer ball? I don’t really play soccer that much, but I’ve never understood why the ball curves in the air when you kick it. For my science project, I wanted to learn about the pressure in the atmosphere and how it affects a soccer ball in flight. I believe that understanding Bernoulli’s Principle may help to explain why the trajectory affects the spin of a soccer ball.…
Part I of this experiment was specifically designed to validate Boyle’s Law, through the use of a homemade barometer. The open-end tube of the barometer, when moved to different heights above or below its equilibrium, visually achieves the application of various pressures (P) in which the volume (V) corresponding to it, can be measured. If pressure (P) times the corresponding volume (V) is a constant within the experimental error, it validates Boyle’s Law as the “volume of a sample of gas at a given temperature varies inversely with the applied pressure”.…

In fluid dynamics, Bernoulli's principle states that for an inviscid flow, an increase in the speed of the fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid's potential energy.[1][2] Bernoulli's principle is named after the Dutch-Swiss mathematician Daniel Bernoulliwho published his principle…
Henry-Louis Le Chatelier’s principle provided to be very valuable for developing more efficient chemical processes. Le Chatelier was a very educated man, earning many degrees in his early life. After only two years as a mining engineer he became a chemistry lecturer in 1877, where he had a very well equipped laboratory. After conducting many experiments his work led him to the study of thermodynamics. His work led to the principle we know today as Le Chatelier’s principle, which outlines ‘how systems in chemical equilibrium maintain their…
Figure (1)-(2) shows the apparatus used for the experiment consist of a acrylic duct of varying cross-section known as a Venturi as shown in Figure (4). The duct has 10 wall tappings for the measurement of static pressure in both convergent and divergent area of a duct. This duct is connected to a flow meter on its right side, where the flow rate is being set as shown in the figure (6). On its left side apparatus is being connected to manometer through 10 different pipes and readings at each of the tapping for each flow rate are being recorded as shown in figure (5). Pressure of water is being controlled by attached hand pump by adjusting valve as shown in figure (3)…
The objective of performing this experiment is to measure the hydrostatic force on a partially submerged vertical surface and to compare the force found in the experiment to the theoretical equivalents.…
The purpose of the experiment is providing an opportunity to students of experience to familiarize with some key aspects of fluid flow in pipe, notably friction losses and verify theory. In this experiment, required equipment are a water tank, piezometric tubes, pump, a stop watch, empty bucket and a digital weight scale. By operating the pump to keep the water is full in the water tank, and measuring the height of water in the piezometric tubes in different height of water outlets. And measuring the flow rate of water in different height outlets with the stopwatch, empty bucket and digital weight scale. After experiments done, use the data of experiments to calculate the velocity and the flow rate of water in the pipe through by the Bernoulli equation. Then compare the calculate results and practical results to approve the theory. The calculated results should very be close to the practical results. There is a necessary discussion of errors due to relevant issues.…

-It was discovered by the Swiss scientist Daniel Bernoulli (1700-1782). According to it, for steady fluid flow, where the velocity of the fluid is high, its pressure is low, and where the velocity is low the pressure is high.…
One of the most common everyday applications of Bernoulli's principle is in airflight. The main way that Bernoulli's principle works in air flight has to do with the architecture of the wings of the plane. In an airplane wing, the top of the wing is soomewhat curved, while the bottom of the wing is totally flat. While in the sky, air travels across both the top and the bottom concurrently. Because both the top part and the bottom part of the plane are designed differently, this allows for the air on the bottom to move slower, which creates more pressure on the bottom, and allows for the air on the top to move faster, which creates less pressure. This is what creates lift, which allows planes to fly. An airplane is also acted upon by a pull of gravity in which opposes the lift, drag and thrust. Thrust is the force that enables the airplane to move forward while drag is air resistance that opposes the thrust force.…
