Bernoulli's Theorem Lab Report

The purpose of this experiment is to learn how use a variety of tools that will aid in the gathering of data. This data is then used to calculate different measurements including, volume and density. The experiment will also further understanding of measurement errors using the data collected.

Poiseuille’s law states the volume in a tube is directly proportional to pressure difference between both ends of the tube and inversely related to the length. Poiseuille’s law was discovered by Jean Louis Marie Poiseuille in 1840 (Poiseuille’s). Jean Louis used his experiments to find the smooth, laminar flow in circular tubing (Jean-Louis). His findings can be described as the flow of blood through the body and bronchial smooth muscle.

Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring

The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.

Being familiar with the formulas of density and unit weight of fluids is important as both values are necessary when it comes to calculating the pressure of the fluids in various regions. Thanks to these formulas, we are also able to prove that different fluids would apply different pressures at the same point.

Every 5 minutes the volume of gas in the test tube was observed and recorded until

In this lab I found there are huge connects between volume and pressure. In the case of

Bernoulli’s principle, which can also be describes as Bernoulli’s equation, describes that for a flowing fluid in an ideal state, its pressure and density are inversely related. In other words, the pressure of a fast moving fluid will decrease as its speed increases. As the term ‘fluid’ describes both liquids and gases, Bernoulli’s principle can also be used to describe many applications with regards to airflow and a fast-moving liquid. (Hall, 2015)

Both the orifice and the Venturi meters produce a restriction in the flow and measure the pressure drop across the meter. The velocity of a fluid is expected to increase as the fluid flows from an open area, to a more constricted area. Assuming incompressible flow, a negligible height change, and steady state, Bernoulli’s equation can be simplified to show the correlation between the volumetric flow rate and the pressure drop. The equation for both meters is as follows:

In this experiment is determine if the water and the unknown liquid has the different of the density. Also an unknown sold can change the density of the two. The requirement used in this experiment were backer, cylinder, and mass measurement.

see more why the results were what they were. The study was done in New Zealand, what is the

Bernoulli’s Principle states that as a moving fluid’s speed increases, the pressure within the fluid decreases. This can be restated as: when a moving fluid’s speed

IF the researchers’ hypothesis is true, what would happen if the air pressure in the top funnel was always greater than the air pressure in the lower funnel?

Purpose: -To understand Boyle’s and Charles’ theory. -To explain the relationship between temperature, and pressure of a gas. - To explain how the pressure in a container of gas is affected when the volume is changed.

4. The flow velocity increases as the flow gets closer to the barrier wall and reduces as it moves away from the wall. This is because as the flow rate is constant (Conservation of mass) while the area of the flow cross section decreases when it gets closer to the barrier wall, the flow velocity increases. This is best understood by referring to the continuity equation,
