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

ME 304 – Experimental Engineering Spring 2013 Lab Report Experiment # 3 Bending of Beams Section # ThTh12 Group # 1 Ömer Ege Çalışkan Serhat Karakuz Noyan Uğur Renda Turgut Soydan 20.03.2013 Abstract In this experiment‚ a simply supported beam is used and the variations of deflection of a simply supported beam with load‚ beam thickness and material are investigated. It is found that the deflection of the beam changes linearly with the load and as the beam

ABSTRACT This report aims to measure the pressure variation and different contributing components of the drag force on a circular cylinder. The devices used in this experiment were a fan‚ closed-channel venturi-shape pipe‚ a Pitot tube‚ circular cylinder with holes of different angles‚ U-tube manometers and a barometer. INTRODUCTION When a fluid is passing through an object‚ it produces a total force on the object. This force is a combined force of lift and drag forces (Anderson 2007). External

An Experiment of Adaptation Introduction: Throughout history of time‚ organisms change in relation to their environment‚ consequently‚ adaptation is an essential property of life. This experiment is designed to test the adaptation of Drosophila melanogaster. This kind of insect is also called fruit flies‚ it has been widely used in scientific research because it has a short life cycle about two weeks and it is easy to keep large numbers of them (Manning). Two groups of this species will be used
Premium Hypothesis
Osmosis in potato cells Aim: To view and examine the effect different concentrations of sucrose solution has on the movement of water across the cell membrane. Hypothesis: That the potatoes will either increase or decrease in mass‚ due to the effect of the different concentrations. Osmosis will occur. Apparatus: * Fresh potatoes * Apple corer * Scalpel * Petri dishes X 10 * 50ml measuring cylinder * Distilled water * Paper towelling * Sucrose solutions:

FLUID MECHANICS Fluids mechanics is a branch of mechanics that is concerned with properties of gases and liquids. Mechanics is important as all physical activities involves fluid environments‚ be it air‚ water or a combination of both. The type of fluid environment we experience impacts on performance. Flotation The ability to maintain a stationary on the surface of the water- varies from he on person to another. Our body floats on water when forces created by its weight are matched equally

If these variables were not to be held constant than the findings of this experiment would be meaningless because there would be no way of desiring if the independent variable was the cause of the changes which were recorded In this experiment‚

I. Lubricants selection and Application A.Viscosity Most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings‚ one should consider viscosity selection for those applications. While most would not use an EP 220 gear oil for an oil-lubricated electric motor bearing‚ many people will use a grease containing that same oil

Fluid mechanics is the branch of physics that studies fluids (liquids‚ gases‚ and plasmas) and the forces on them. Fluid mechanics can be divided into 1) fluid statics‚ the study of fluids at rest; 2) fluid kinematics‚ the study of fluids in motion; 3) fluid dynamics‚ the study of the effect of forces on fluid motion. Fluid Mechanics Overview Fluid is a substance that is capable of flowing. It has no definite shape of its own. It assumes the shape of its container. Liquids and gases are
