    Objectives With the use of similar apparatus equipment through constant temperature at atmospheric pressure, the viscosity will be determined by tests in two different fluids in sets of two ball trials; along with data collected from a third set. By reducing errors and obstructions it will justify data for better discuss and calculated results, supporting the theory beyond the lab report to resonate in helping others comprehend the experiment. Procedure The experiment was conducted in a repetitive manner with slight variation amongst different materials within similar apparatus devices that facilitated the lab to fullest diversified potential. The equipment pertaining to the lab such as the cylinder and balls were…

    Lab Report: Density and Viscosity Problem: What is the effect of density on the viscosity of a substance? Hypothesis: Density will affect the viscosity of a liquid. The order of the liquids from most dense to least dense is: syrup, detergent, water, oil Background: Density and viscosity are closey related in which they both affect one and other. Denisty has many factors like weight, mass, and volume. To work cohesivly there are different things we must pay attention to. Density is how closley…

    to flow, known as viscosity. In this experiment will change the oobleck’s viscosity by changing its thickness. Additionally, applying any pressure to oobleck helps to changes its viscosity. A quick tap on the oobleck cause it to feel hard, this is due to the cornstarch coming together; but slow pressure causes the cornstarch particles to move allowing it to feel similar to water. In this experiment will be using…

    A series of viscosity measurements were conducted on two specimens, one for 90% BSS modified binders, other is for the Neat asphalt, both of them have the same process but different temperature but same rpm. For BSS viscosity measurement, shearing was applied using spindle V-73 at a speed of 1, 2, 3, and 4 rpm. Viscosity measurement was conducted using Brookfield Viscometer (ASTM D4402). In this test, the viscosity, torque, and shear stress are determined while applying a rotational shear on the…

    Viscosity and Flow Rate by Hasnain S. and Vinh T. What is Viscosity: Viscosity is the measurement of how fast a fluid will flow. In other words, it is the “thickness” or “thinness” of a fluid. The internal friction or resistance it has as well as the temperature in which the fluid is at determines the viscosity of the substance as well. If there is more internal resistance or friction, then the particles of the substance won’t slid past each other as easily and therefore make the substance…

    substance that deforms continuously when subjected to a shear stress. A simplified definition is that it is a substance that is able to flow smoothly and changes it’s shaped when a force is acted upon it. There are different types of fluids. Ideal Fluids and Newtonian as examples. An ideal fluid is a substance that has zero viscosity and is considered to be incompressible (density is constant). [2] In reality, there is no such thing as ideal fluids as there are always viscous effects, but are…

    This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity distribution for flow of a Casson fluid in a very narrow blood vessel. The blood in this case is treated as a two phase fluid where the phases are governed by a constitutive equation relating shear stress, viscosity, and shear rate. This equation would…

    There are five main types of these enigmatic substances. To start with, there are the thixotropic fluids. Over time, the viscosity of these fluids decreases when stress is present. An example of thixotropic fluids is honey because the longer it is stirred, then the less solid it becomes. Second, there are the rheopectic fluids. When stress is applied over time, then the viscosity increases. Cream is an excellent example of rheopectic substances because the longer the cream is whipped, then the…

    Airfoil is placed approximately 1 inch away from the tip of the nozzle. The height of the nozzle is then adjusted so that dye is injected on the middle of the front of airfoil. After 30 seconds, red dye is released and the pattern is recorded by cell phone camera (School of Mechanical Engineering, 2016). Results The measured temperature and kinematic viscosity of the water are listed in Table 1. Temperature of the water tunnel is measured by thermocouple at the beginning of the experiment.…

    impossible without the support of a computer [12]. These translators are numerical discretization methods like Finite difference, Finite volume methods and Finite element. Actually we have to break down our problem into small parts because the discretization is based on them. Then programs are written to solve, generally they written in typical languages like Fortran and C. The programs are run on workstation or supercomputers. Finally we get the simulation results which we can compare and…
