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

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules

The evidence for assuming the dispute as a debate of theories and methodologies and not only as a debate of therapies is in the by-products emerged as consequence of the dispute. After Pitcairne’s publication of his answer to Brown‚ a brief anonymous manuscript appeared‚ entitled Apollo mathematicus –which Cunningham attributes to Eizat-. In it‚ the author criticizes the mathematical approach developed in physics and physiology. By contrast‚ he praised the value of the Aristotelian qualitative explanations

SPE INTERNATIONAL Abstract Sidetracking has been proven to be a cost saving solution over drilling new horizontal wells to increase production from existing wells. Most problems that might be encountered when removing casing can be identified prior to beginning a lining removal job. By identifying these potential problems‚ the proper equipment can be used effectively to keep the job running smoothly. Technical advances in mill design such as the development of a cutting structure that effectively

The drag‚ FD‚ on a sphere located in a pipe through which a fluid is flowing is to be determined experimentally. Assume that the drag is a function of the sphere diameter‚ d; the pipe diameter‚ D; the fluid velocity‚ v; and the fluid density‚ ρ. (a) What dimensionless parameters would you use for this problem? (b) Some experiments using water indicate that for d = 0.005 m‚ D = 0.0125 m‚ and v = 0.6 m/s‚ the drag is 6.5×10-3 N. If possible‚ estimate the drag on a sphere located in a 0.6 m diameter

Description The patient presents with dementia‚ poor posture (her chin close to her chest) and dislikes solids‚ there for has to be assisted to feed and chooses only to consume liquids. Her communication skills are also poor and doesn’t have the capacity to engage in a flowing conversation but has the ability to answer a question using the words ‘yes’ or ‘no’ or by saying individual words. I was given the task of feeding the patient at lunch time as she requires one to one support at meal times

The Split Personality of Hydraulic Fracturing There is wide agreement among most experts and the public that the current energy sources we use in the United States are in need of a replacement. Reliance on the fossil fuels of coal and oil are problematic for at least two reasons: their negative impact on the environment (both in extraction and their use) and the reliance on supplies of these from other countries‚ which has created problems on the geopolitical front. Nuclear fission remains a controversial
