Structure, Properties and Treament of Steel Assignment

Structure, Properties and Treament of Steel - Assignment Example The flow pattern shows an effective decrease in cross section beyond the orifice plate, with a maximum velocity and minimum pressure at the vena contract. The flow pattern and the sharp leading edge of the orifice plate which produces it are of major importance. The sharp edge results in an almost pure line contact between the plate and the effective flow, with the negligible fluid-to-metal friction drag at the boundary. Measuring fluid flow with an orifice and differential pressure manometer requires that the effect of the fluid over the manometer liquid be taken into account. The main intention of this experiment is to explore the relationship between fluids and the media through which they travel by exploring the events that occur in the movement of a fluid from one point to another and the characteristics of the fluid itself. These may include may include pressure, momentum, viscosity, turbulence, velocity of the fluid and friction. It also considers the impact of foreign bodies and flow equipment along the path of the fluid This experiment will allow students to learn the method of measuring air flow velocity using Pitot tube. The student will understand the working principle of Pitot tube as well as the importance of Bernoulli equation in deriving and calculating the velocity by exploring the developing boundary layer in the entry length of a pipe. The main objective of this was to determine the vital discharge coefficient for an orifice plate meter installed within an air flow pipe and using the static pressure tapping’s provided, to investigate the pressure distribution along the pipe downstream of the orifice plate. Essentially fluid dynamics in physics is considered as a sub-discipline of fluid mechanics, and deals with the relations between velocities and accelerations and forces exerted by or upon fluids in motion. This field encompasses aerodynamics, (the study of air and other gases in motion) and hydrodynamics

Theories in mythology - Essay Example All mythic heroes are invariably ethical and moral. Most of the stories depict his hardship and travails in pursuit of a morally acceptable equilibrium. His persistence in the face of adversity and his dedication to his convictions are the other hallmarks of a mythic hero. But most importantly, irrespective of the human or super-human quality of the Hero, the mythology surrounding him is constructed to enlighten people on appropriate behavior and give them a sense of direction during phases of ambiguity. During the times of its conception and application, mythologies were intricately woven into the fabric of society. It is to be noted that for primitive people mythologies were the predominant source of information and entertainment. Hence, it becomes difficult to distinguish between the theoretical and practical sides of these stories. In the context of this uncertainty, it is inevitable that various and often conflicting interpretations of the meaning and significance of mythologies are formed. So no particular interpretation is universally acceptable. This leads to definitions that are only valid within a certain social and cultural unit of organization. At the time of its origins, human societies were largely feudalistic and paternalistic. This reality is also reflected in much of the literature of these times, which were again component parts that comprise the mythology. Every social order has had its ruling class. And mythologies were frequently employed as a means of keeping the status quo. Hence, the nobility, which is generally assigned the task of creating much of the mythology, did not adhere to principles of good scholarship. They were given a free hand to twist and tweak the tales to suit the ruling interests. This makes futile all attempts to arrive at a generally agreed definition for Mythology. Dardel assertion that myths are neither true nor false can be explained the following way. Many mythologies are
