4) Pascal’s law – a principle of fluid properties that states when pressure is applied to a confined fluid, the pressure is transmitted, undiminished, throughout the fluid. Additionally, this pressure acts on all surfaces of the container, at right angles to those surfaces. Discovered by French scientist Blaise Pascal in 1653.…

The purpose of the Cartesian diver is to demonstrate the compressibility of a gas, the incompressibility of water, Boyle's law, Pascal's law, and Archimedes' law. Boyle's Law states that under conditions of constant temperature and quantity, there is an inverse relationship between the volume and pressure for an ideal gas. Pascal's Law states that if pressure is applied to a non-flowing fluid in a container, then that pressure is transmitted equally in all directions within the container. Archimedes' principles is an upward force on an object immersed in a fluid (a liquid or a gas), enabling it to float or at least to appear to become lighter. If the buoyancy exceeds the weight, then the object floats; if the weight exceeds the buoyancy, the object sinks. It was Archimedes who first discovered buoyancy…
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)…
Through this project, our goal was to demonstrate an understanding for the concepts of pressure, Newton’s Laws, Bernoulli’s Principle, volume flow rate, efficiency, power, potential and kinetic energy, and work. It provided a summation for most of the topics covered in this course.…

Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17th century. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects. You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas.…

Bernoulli’s Equation can analyse the flow of the wind. It is basically to determine the pressure imposed by the wind to the structure of the bridge. Bernoulli’s Equation states that,…
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.…
