Viscosity Science Lab Purpose: To determine of changing the viscosity will affect the time it takes for a marble to flow through a liquid. Hypothesis: If a marble is dropped into dish soap and corn syrup‚ than I predict that the marble in the dish soap will travel faster than the marble in the corn syrup because I know that the viscosity of the corn syrup is thicker than then the viscosity of the dish soap. Also‚ the particles in the corn syrup are more compact than those in the dish soap

and incompressible flow is used. However in the real case‚ the viscosity cannot be neglect and the density of the flow is not always constant. Thus Bernoulli’s equation is not always correct. For the lab‚ it is reasonable to assume the flow is inviscid and incompressible. Firstly‚ the pitot was placed at the center of the flow. The skin friction (effect of viscosity) is inversely proportional to distance. Therefore the effect of viscosity can be neglected in the pitot. Secondly‚ the speed of the flow

Lab report: Viscosity of Liquids Introduction This experiment focuses on measurements of different trials of various concentrations. The collected data is used to compare and contrast to the ideal binary solutions and their components. The Ostwald viscometer is a useful laboratory equipment to measure the viscosities of many binary solutions. Background Molecules have the ability to slide around each other‚ result in a flow. Such a flow has a resistance called viscosity. Microscopically

times people use terms associated with mental illness to describe themselves or others that son’t actually have a diagnosis. Because there are so many different meanings‚ the actual meaning can often be skewed. Until our society and world discard the false definitions of mental illness‚ it will be unable to move forward in understanding those with diagnosis’s better.

True Blood and Gender Presentation In The HBO television series True Blood‚ there is a wide variety of characters that could be discussed. I’m going to focus on the three leading female characters and the stereotypes that keep the audience coming back for more. Sex sells or at least makes everything a bit more interesting and with this show there is plenty of sexual innuendo to go around. For such a small town Bon Temps sure has its share of hot temptresses. To focus on the ladies means I will

Measuring the Viscosity of Motor Oil ME331 Laboratory Assignment #1 Prepared for: Prof. Sangeorzan Submitted by: Abstract An experiment was conducted to model the effect of temperature on the viscosity of motor oil and compare the results to commercial values established by the Society of Automotive Engineers (SAE) for SAE 30‚ SAE 40 and SAE 5W30. The viscosity of the oil sample at eight temperatures between 20 °C and 55 °C was determined using a rotary Brookfield DV-II+ viscometer

examine the viscosities of ideal and non-ideal solutions. The ideal being the toluene/p-xylene and the non-ideal being the methanol/water. The second objective of this lab was to investigate the temperature dependence of viscosity (Halpern‚ 17-1). Introduction: Viscosity is the resistance to flow of a certain fluid. In this experiment two solutions are used. According to the definition of viscosity mobile liquids have a relatively low viscosity. Fluidity is the reciprocal of viscosity‚ given
