The Elvis Experiment
Introduction: In this experiment we will determine how the difference in length and diameter of a blood vessel have an effect on the resistance of blood flow and how the viscosity of blood will also effect the resistance of blood flow in a blood vessel.
Observation: My mom is a big Elvis fan and she always wondered how his health affected his death. Knowing that he had high cholesterol and high blood pressure I decided to do an experiment on what factors may have had an effect on his high cholesterol and high blood pressure.
Hypothesis: I know that the longer the length of the tube, the smaller the diameter of the tube, and the thicker the viscosity of a substance the greater the resistance, therefore it will take longer for the substance to pass through it. Controlled Factors:
Independent: length, diameter, viscosity
Dependent: Amount of time for the fluid to pass
Experimental Design: Procedure A: Length
Using a short 40 cm tube attach it to a ring stand with a clamp.
Arrange and position the tube making sure that it is horizontal.
Put an empty beaker at the end of the tube to catch the substance that flows through the tube.
Fill a 100 ml graduated cylinder with water, adding a drop of food coloring to it. (Food coloring will make it easier to see the fluid as it flows through the tube)
Using a funnel, pour the 100 ml of water

    Flow tube radius change has a direct effect on flow rate. As evidenced in this lab, when flow tube radius was increased, the flow rate was also increased. They are directly proportional. As evidenced from the text, when flow tube radius increases in a blood vessel, the flow rate is much more free flowing and flows a lot quicker as the radius is increased. When starting with 1.5mm of radius, the flow was very slow, yet when increased to 2mm, 3mm, and eventually to 5mm, the flow within the blood vessel incrementally increased.…

    Coal mining, particularly surface mining, leads to large areas of land being temporarily disturbed. The mine workings collect and conduct water that is in contact with the widespread pyrite, a mineral that produces iron and sulfuric acid when exposed to air and water. In this lab, you will see first-hand the reasons why mine drainage can be harmful to the local drainage system if left untreated.…

    Part 1 sought to measure the movement of water in response the addition of various concentrations of NaCl. It was hypothesised that as the concentration of NaCl increases, then the amount of lysis of the red blood cells would decrease. Part 2 aimed to determine how permeable red blood cell membranes were to various solutes. It was hypothesised that as the lipid solubility of solutes (Kether) increases, as does the permeability coefficient. Part 3 of the experiment aimed to produce and measure diffusion potentials across two different membranes of semi-permeability. It was hypothesised that as the voltage increases, as does the log of the concentration gradient.…

    Before we conduct the experiment, we must first understand what viscosity is. “Viscosity is the quantity that describes a fluid's resistance to flow”.1 It is essentially fluid friction and transforms kinetic energy of motion into heat energy, just as friction (“the force between surfaces in contact that resists their relative tangential motion”) does between two solid bodies. All fluids express some amount of viscosity. An ideal fluid has no internal friction between the molecules, meaning that it is not viscous. The reciprocal of viscosity is fluidity (“the physical property of a substance that enables it to flow.”)2 Thus, fluids that are high in viscosity tend to flow slower while fluids that are low in viscosity tend to flow faster. Different liquids have different forces: the larger the intermolecular force, the more viscous it is and vice versa.…
