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.

What of Embalming Fluids? Our earliest knowledge of when/where embalming first occurred was around over 5‚000 years ago in Egypt. Then‚ embalming was used for religious purposes and to keep the body from decaying until Christianity began to dominate; Embalming purposes were turned into being used for body preservation for dissection and studying. In the U.S though‚ there originally wasn’t any true way of embalming for funeral reasons. Originally we just used ice in order

University’s wooded areas‚ the oldest was created in 1989 the second was created in 1994 and the youngest plot was created in 1999. For the hypothesis to be tested‚ there were soil PH meters to test the amount of PH in each plot’s soil. The hypothesis was incorrect; there was not a significant difference in the means of the PH from the oldest plot compared to the youngest plot. Introduction The definition of vegetation is plants considered collectively especially those found in a particular area

food nutrition is protein. There is no high protein food‚ even if eating more carbohydrates‚ exercise how hard‚ it is difficult to get muscle full of body contours. The protein is not only the nutrients needed for muscle development‚ but also the body after the strenuous exercise to repair the damage necessary. Therefore‚ high-protein foods should be included in the daily diet. 1‚ eggs are the most natural‚ the most useful food to build muscle. They not only contain rich protein‚ but also have a lot

Proteins are also essential nutrients for the human body. They are important in body tissue‚ and can also serve as a fuel source. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. We need protein in our diet to help our body to repair cells and make new ones. The human body needs a lot of amino acids to maintain good health. Protein is also important for growth and development in children‚ teens‚ and pregnant women. Proteins are polymer chains

Liquid fuels such as gasoline‚ diesel‚ fuel oil light‚ fuel oil heavy or kerosene have to be atomized and well mixed with the combustion air before burned. Therefor nozzles are used. Nozzles are divided into two groups: Pressure atomizers and twin-fluid atomizers. 5.1.1 Pressure atomizers Pressure atomizers are differed into turbulence nozzles and liquid sheet nozzles. At both types of nozzles the energy from the liquid pressure is converted into kinetic energy and a small part of it into forming

Armadillium vulgare taxis response to different pH levels. Abstract The terrestrial isopod‚ Armadillium vulgare is commonly referred to as a slater or pill bug. Since transitioning from the sea to land and originally colonizing in Mediterranean regions‚ it has adapted throughout evolution to inhabit local microhabitats. The pill bug is bound by several parameters and also has specific requirements that need to be met for optimal biological functioning. As such‚ behavioural and physiological

Lab #6: pH Effects and Enzyme Concentration on Catecholase Activity Abstract: This experiment examined the effect on how the changes in pH balance of potato juice affected the enzyme activity‚ structural stability and solubility. Introduction: Enzymes are macromolecules that allow chemical reactions to occur. They function as biological catalysts. A catalyst is a substance that is involved in‚ but not changed by or consumed in‚ a chemical reaction. The amount of energy required for a reaction

High-Protein Diets Christine J. Williams SCI 241 September 19‚ 2012 Diane Carson High-Protein Diets Proteins are a vital nutrient that must be provided by one’s diet. Bones‚ skin‚ muscle‚ hair‚ and most other tissues are made up of proteins. The continuous replenishment of new protein from one’s diet keeps the body functioning properly. When a person is consuming a high protein diet‚ it is inevitable to be on a low carbohydrate diet as well. There are a lot of foods that contain protein and
