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.

Due to the intervertebral disc specific structure and the interactions between nucleus pulposus and annulus fibrosus‚ it is capable to resist high compressive loads and provide spinal mobility (Tang‚ Liu‚ & Zhang‚ 2014). The nucleus pulpous is capable to endure high compressive forces because of its high water content‚ low permeability and osmotic properties (Galbusera et al.‚ 2014). It works by distributing hydraulic pressure in multiple directions within each intervertebral disc under compressive

Experiment 1 Fluid Flow In A Smooth Pipe Abstract In this experiment‚ three variable flow meters are used to alter the flowrate. Changes in pressure drop due to the change in flowrate are then observed from the three pressure gauges that can measure pressure at different range and recorded. The shift from laminar flow to turbulent flow is seen from the results recorded‚ but it is observed more clearly from the water-soluble dye experiment that was carried out by the demonstrator. Laminar flow

2102ENG : Soil Mechanics Hydrometer Analysis Semester 2‚ 2012 Introduction: The hydrometer test is an application of Stokes Law‚ which in essence states that larger particles fall more quickly in a suspending fluid‚ while finer particles remain in suspension longer. The time at which the hydrometer readings are taken determines the size of particle remaining in suspension‚ while the reading on the hydrometer determines the amount of that size. Aim: This

INTRODUCTION. SOLIDS‚ LIQUIDS AND GASES have properties that are use to describe how they behave‚ e.g. for solids it has a definite shape‚ you can hold a solid rock in your hand. You can push on a solid brick wall. Scientists say a solid is something that has shape. A solid resists any change in its shape. TASKS 2. LOOK AT THE PICTURES BELOW FOR SOLID‚ LIQUID AND GAS AND WRITE DOWN THREE PROPERTIES OF EACH? Wood as a Solid. Solid has a fixed shape Its particles are tightly held together

Aim The purpose of this experiment was to plan‚ design‚ fabricate and test the structure of a microfluidic flow structure. Background Microfluidic structures are a relatively new topic of study. While the concept of fluids and the study of the flow of fluids through all sorts of various forms of ducts‚ environments and scenarios have been extensively studied by some of the greatest minds of in history‚ the novelty of microfluidics is not surprising. This is due to the fact that despite the fact

Effect of Temperature on Polymers: Solids on heating eventually melt to form a liquid. With polymers it is not so simple rubber on cooling (in liquid nitrogen) becomes brittle or glassy. Many polymers have a mixture of ordered (crystalline) regions and random (amorphous) regions. In the glassy state‚ the tangled chains in the amorphous region are frozen so movement of chains is not possible the polymer is brittle. If the glassy material is heated‚ the chains reach a temperature at which they
