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)

MEASURING AND MODELLING HYDRAULIC FLUID DYNAMICS AT HIGH PRESSURE - ACCURATE AND SIMPLE APPROACH. International Journal Of Fluid Power‚ 13(2)‚ 51-59. ASTRACT: Dynamic properties of hydraulic fluids have to be taken into account in ever increasing fluid power applications. The main reasons are increasing accuracy demands in control and modeling‚ as well as increasing operating pressure and temperature ranges. Moreover‚ the already wide spectrum of different hydraulic fluids is also expanding all the time

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

Lecture No. 5 CLASSIFICATION OF FLUID FLOW AND THE CONTINUITY EQUATION 5.1 Classification of Fluid Flow Uniform flow If the velocity of the fluid is the same in magnitude and direction at every point in the fluid the flow is said to be uniform. Non-uniform flow A non-uniform flow is one where the velocities at different points at a given instant are not the same. Every fluid that flows near a solid boundary will be non-uniform because the fluid at the boundary takes the velocity of the

CEIC2001 – Fluid Mechanics Notes Fluid – A substance which is capable of flowing. A fluid is also a substance which has no permanent resistance to change in shape i.e. a solid can resist a shear stress‚ τ by static deflection; a fluid cannot‚ any shear stress applied to a fluid will result in the motion of that fluid for as long as the shear stress is applied. τ=FA Where F = force which is tangent to a surface (shear force)‚ A = area of moving plate in which shear force is applied to.

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 flows past objects have been studied extensively because of their many practical applications. For

1. Using diagrams and/or graphs‚ explain the following terms: a. Pressure Head pressure head [′presh·ər ‚hed] (fluid mechanics) Also known as head. The height of a column of fluid necessary to develop a specific pressure. The pressure of water at a given point in a pipe arising from the pressure in it. b. Total Discharge Head Total discharge head refers to the actual physical difference in height between the liquid level in the pit and the highest point of the discharge pipe or water level in

CBE 6333‚ R. Levicky 1 Potential Flow Part I. Theoretical Background. Potential Flow. Potential flow is frictionless‚ irrotational flow. Even though all real fluids are viscous to some degree‚ if the effects of viscosity are sufficiently small then the accompanying frictional effects may be negligible. Viscous effects become negligible‚ for example‚ for flows at high Reynolds number that are dominated by convective transport of momentum. Thus potential flow is often useful for analyzing external
