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

Fluid Report 2 In the derivation of Bernoulli’s equation‚ the assumption of the inviscid 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

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

objective of this lab was to find and 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

INTRODUCTION The measurement of fluid flow is very important in our daily life from measurements of blood-flow rates in human artery to the measurement of liquid oxygen in a rocket. In this experiment‚ students are to adapt to various ways to measure the flow of essentially incompressible fluids by using the flow measuring apparatus. Students will also be able to understand the application of Bernoulli’s equation in this experiment. The flow is measured by using a venture meter‚ an orifice meter
