Hydrostatic Pressure - Lab Report Example A fluid in this condition is known as a hydrostatic fluid (Myers, 2006). So our Hydrostatic pressure lab was to determine the hydrostatic pressure of water on a flat surface, adding weight and then filling the tank with water to the point where the apparatus was in equilibrium in order to calculate the force on the flat surface using the given equations. The Fluid Mechanics laboratory provides a â€Å"hands on† environment that is crucial for developing students understanding of theoretical concepts (Damodara Reddy, 2012). Fluid mechanics laboratory is where fluids and their flows are studied and observed such as â€Å"Pressure variations of compressible fluids when they are allowed to flow through convergent divergent nozzles, calibration of pressure gauges and theoretical demonstration of different laws of fluid mechanics and others† (Desmukh, 2009). The objective of this experiment was to â€Å"calculate the hydrostatic force a fluid exerts on a submerged plane surface† and then liken the experimental hydrostatic force to the theoretical hydrostatic force. Furthermore, we will calculate the center of pressure for a plane surface partially submerged in a fluid and then for the plane surface full submerged in the fluid. Firstly, the following measurements were made; of quadrant’s end face, lever arm length and the distance between pivot and the lower edge. Now with the apparatus placed steadily on the stall, position the balance arm on the knife edge pivot and hang the weight pan from the balance arm.The apparatus was made use of adjustable feet and spirit level. Now the counterbalance was rotated until the balance is level and the counterbalance was to remain at the same position for the whole experiment.Now a mass of 50g was positioned on the weight pan and water was added until the balance arm was horizontal. The mass on the water pan and water level were measured Now we increment the

Critical thinking - Case Study Example This amounts to 8.5% of the total population. The American Indians are 16 people, while the Asians are 12. In percentage terms, the Indians amount to 0.77%, while that of the Asians was 0.58%. There are also other minority tribes, such as Eskimos and the Pacific Islanders. Their total number amounts to 98, which is 4.9% (Statistical abstract of the United States, 17). St. Juan is a city found in Hidalgo, one of the counties of the state of Texas. The city is located at 26Â °1133"N 98Â °9 10"W, and has an area of 11 square miles. In 2011, the city had a population of 34,091, which was an increase of approximately 30%, as compared to the statistical figures of 2000 (Statistical abstract of the United States, 36). The number of males was 16, 498, and this is a percentage of 48.4%. The female population amounted to 17,593, which represents a percentage of 51.6% (Statistical abstract of the United States, 21). The largest numbers of people in St Juan are the Hispanics, whose number was 32,734 representing a percentage of 96.7%. The Asians were 47, and the blacks were 32, which was a percentage of 0.1 and 0.09 % respectively. The total number of white people was 1012, and this was a percentage of 3%. The minority tribes of the Eskimos and the Pacific have amounted to 10 people, and this contributed to a percentage of 0.03% (Statistical abstract of the United States, 25). The reason as to why the Whites and the Hispanic are the majority in these cities is because they assimilated the minority groups of the Eskimos, the Pacific’s and the Black Americans. The Eskimos and Pacific’s are small in number; this makes them vulnerable to the dominant tribes of the Hispanics and the Caucasians. The Hispanics and the Caucasians intermarried with them, and because of their dominance, they were able to assimilate these groups. This led to the increase of the Hispanics in the St Juan city, and the increase of the whites at the city of St. jo. Intermarriage is an
