acceleration was found‚ we can use Newton ’s 2nd Law (F=ma) and Terminal Velocity [F(gravity)=F(air resistance)] to determine the forces acting on the object. Our two models are defined with: Laminar Flow (for a sphere): F = 6 π η r v where η is viscosity‚ r is the radius of the sphere‚ and v is the relative speed of the sphere Turbulent Flow (for a sphere): F = (1/2) π ρ Cd r2 v 2 where r and v are the same as above‚

zero due to the assumption made that fluid could be treated as “inviscid” meaning the viscous effects can be negligible. However it soon arose that this was not the case and in fact‚ viscosity plays a very large role in finding flow behaviour and resulting forces on a body in a flow. The main way in which viscosity affects the behaviour of flow is through the “boundary layer” meaning a thin layer of fluid next to the surface of any body in a moving fluid. The increase and behaviour of the boundary

The algae were pounded and dried before oil was extracted. The extracted oil had undergone transesterification. This reaction was often catalyzed by the addition of acid or base catalyst. After transesterification biodiesel produced went through viscosity test‚ flammability test and luminosity test to find out how effective it is compare to commercial product. The data were recorded and tabulated. Based on the observation done‚ it was found out that Acrosiphonia mertinsii and Sargassum crassifolium

CHAPTER ONE 1.0 INTRODUCTION Natural rubber is produced by over 2000 plants species and its main constituent is poly (cis-I‚4-isoprene).a highly unsaturated hydrocarbon. Since 1914 there have been efforts to investigate microbial rubber degradation: However‚ only recently have the first proteins involved in this process have been identified and characterized and have the corresponding genes cloned. Analysis of the degradation product of natural rubber and synthetic rubbers isolated from various

The Marsh funnel is a simple device for measuring viscosity by observing the time it takes a known volume of liquid to flow from a cone through a short tube. It is standardized for use by mud engineers to check the quality of drilling mud. Other cones with different geometries and orifice arrangements are called flow cones‚ but have the same operating principle. A modern plastic Marsh Funnel In use‚ the funnel is held vertically with the end of the tube closed by a finger. The liquid to be

FALL 2012 ME 305 FLUID MECHANICS I EXPERIMENT 1 MEASUREMENT OF FLUID PROPERTIES PREPARATION: In this course‚ you will conduct the experiments at the Fluid Mechanics Laboratory‚ by yourselves‚ without any help or instruction from the teaching assistants. You must read the lab sheet thoroughly and understand what you are expected to do (and why) for each experiment‚ before coming to the lab. At the end of each experiment‚ you will have to do certain calculations‚ present and plot (when asked)

7.3 Flow Rate and Viscosity (pg 153) Q1. If the flow rate in a pipe is 2 L/s‚ what does that tell you about how fast the water is moving. A1. It tells me that the water is moving fast through the pipe at 2 litres per second. If there were 60 seconds you would have 120 litres. Q2. When you tip a bottle of syrup upside down‚ it takes a longtime for all the syrup to pour out. Explain this using the terms “viscosity‚” “cohesion‚” and “adhesion.” A2. Syrup takes a long time to empty

Transverse wave Different kind of waves Speaker and non- Newtonian fluid experiment Seaker and non- Newtonian fluid experiment A non-Newtonian fluid is a fluid whose flow properties cannot be described by a single constant viscosity. An inexpensive‚ non-toxic example of a non-Newtonian fluid is a solution of corn starch (corn flour) and water‚ sometimes called oobleck. The application of force - for example by stabbing the surface with a finger‚ or rapidly inverting the container

and equipment limitations‚ which caused the data points obtained to vary from the expected theoretical values. The factors and assumptions made were that the minor head losses were negligible‚ which might not have been the case. The density and viscosity values obtained from the data sheet might have also introduced error into the results. Introduction Theory and Principles In this experiment‚ the theory and principles in used is the loss of energy and total head of fluid due

CHAPTER ONE 1.0 INTRODUCTION This report is a practical experience acquired by me in the course of my industrial training at Druckfarben Nigeria Limited (DFN) under the student industrial work experience scheme (SWIES). In the earlier stage of science and technology education in Nigeria‚ students were from their respective institutions without any technical knowledge or working experience. It was in this view that students undergoing science and technology related courses were mandated in different
