Design - Essay Example This paper presents the introduction to cone calorimeter test, the experimental procedure for conducting the experiment, the test results obtained and finally the results obtained are evaluated and a conclusions is drawn based on the results. The name cone calorimeter was coined from the shape of truncated conical heater that was developed by Dr. Vytenis Babrauskas who used the equipment to irradiate a test specimen of size 100 mm by 100mm. most of the laboratory contain the FTT cone calorimeter as it is compact and easy to use. Exhaust system: It comprises of the hood, gas sampling ring probe and an exhaust fan which are manufactured from stainless steel. The flow can be controlled and the equipment also allows for orifice flow measurement. Split shutter mechanism: This system is used to protect the sample area before conducting the test. It ensures that the initial mass measurement is constant. The operator is given extra time before starting the test. The shutter system also prevents premature ignition of highly ignitable materials (Source: Johan, A. 2002. Cone Calorimeter –A Tool for Measuring Heat Release Rate. Finland: Abo Akademi process chemistry center. [Online]. Available at http://www.tut.fi/units/me/ener/IFRF/FinSweFlameDays09/4B/LindholmPaper.pdf . Accessed august 20, 2009. ) The oxygen consumption principle is used in the formulation of empirical observation in a cone calorimeter test. The underlying principle used stipulates that the heat released is directly proportional to the oxygen consumed. Measurement of the oxygen concentration at the exhaust duct and the volumetric flow rate of air give data that is used in the computation of the rate of oxygen consumption. The heat released in a cone calorimeter is given by; The main objectives for conducting this experiment are to determine the rate of heat

Ecology of Public Administration, Bureaucracy, and the understanding Essay

Ecology of Public Administration, Bureaucracy, and the understanding of the relationship between democracy and publi administration - Essay Example This is because an administrator is attached to a set of systematic rules that must be followed while politician is entitled to popular rule. The public also plays a significant role in the conduct of administration but not in politics. Richard Stillman also believes that the Constitution was primarily created for the people court, foreign affairs, defense, money and trade relations (Stillman, 2009). This implies that a Constitution shares some fundamental principles with Public Administration because they all follow systematic rules. Therefore, it is difficult to incorporate popular rule, democracy, into the constitution just like Wilson suggested. Therefore, Administration should particularly focus on teaching people the kind of a government system or rule they demand or desire, and how to achieve it. John Gaus had perceived a bright light in applied social science. Through an ecological measure to Public Administration, Gaus believed that new or renewed patterns, in the public administration or institutions, could be achieved from individual people living in the dynamic times (Stillman, 2009). Ecology, in Public Administration, is a significant tool for directing, comprehending and modulating shocks of change, in the current dynamic world. Ecology, in actual sense, means an area or environment of numerous organisms that co-exist in a noble point of natural equilibrium (Stillman, 2009). Ecology is a broad idea in the sense that it deals with the large existence of interrelations of all the living organisms with their environment. Ecology entails balance and existence of nature in a vicious circle that one thing results into another and creates a point of balance. These ecological elements include climate, soil, people, plants and many other things in the ecosystem. Therefore, acc ording to Gaus, ecology is a vital complex analogy that explains the complex Public Administration system (Stillman, 2009). Gaus explains that a
