Canada T6G 2W2 Dear Mr. Demirdal‚ Drilling mud is important in the petroleum industry. Drilling mud can be composed of various types of clay. All the clays have their unique properties and when prepared with water‚ they will exhibit different viscosity‚ gel strength‚ and most importantly‚ the rheological characteristic of the drilling mud. We are required to observe the difference between Bentonite‚ and Attapulgite clay in both salt water and fresh water. It was also required to differentiate the

Abrasive flow machining 1. Introduction Abrasive flow machining (AFM) was firstly developed fifty years ago by Extrude Hone Corporation‚ USA. By using the liquid viscoelastic material with easy flowability made of polymer and abrasive grains‚ AFM can be used to polish‚ deburr and radius for the workpiece. There are three kinds of AFM: one-way AFM‚ two-way AFM and orbital AFM [1]. In this case to manufacture the cylinder heads‚ consider of two-way AFM is much more widely used and its technology

bar and the temperature is 22°C. When inflated prior to launch‚ the balloon is spherical (radius 1.3 m) and the inflation pressure equals the local atmospheric pressure. 2.29 The viscosity of SAE 10W-30 motor oil at 38°C is 0.067 N · s/m2 and at 99°C is 0.011 N · s/m2. Using Eq. 2.8 for interpolation‚ find the viscosity at 60°C. Compare this value with that obtained by linear interpolation. 2.34 The velocity distribution for water (20°C) near a wall is given by u = a(y/b)1/6‚ where a = 10 m/s‚ b

help us to calculate the flow rate of the water. It is important to study how to use the Reynolds number to calculate the flow pattern and also the Reynolds numbers can be used to calculate other properties such as density‚ velocity‚ diameter and viscosity. We must understand that Reynolds number is a ratio of inertia to viscous effect of a flow. The experiment was conducted in UNITEN lab with my lab mates and was supervised by my lab instructor Mr. Ibrahim. The procedure and rules which has been taught

Classification of Settleable Solids There are different factors to be consider in choosing the type of sedimentation to be used‚ some of it are particle size‚ viscosity‚ solid and solution densities as well as the characteristics of the particles within the slurry. In this figure‚ it illustrates the relationship between solid concentration‚ interparticle cohesiveness and the type of sedimentation that

citric acid on the rheological properties of cornstarch pastes were studied by steady shear and dynamic oscillatory viscoelasticity‚ intrinsic viscosity measurements and microscopic observation. The pH of cornstarch dispersion was adjusted between 6.0 and 3.0. The viscosity of the pastes was increased by lowering the pH (between 5.5 and 3.6)‚ while the viscosity of samples with pH below 3.5 decreased further than that of the control (pH ) 6.3). Citric acid promoted the collapse of starch granules; however
