Design - Essay ExampleThis paper presents the introduction to cone calorimeter test, the experimental social function for conducting the experiment, the test results obtained and finally the results obtained atomic number 18 evaluated and a conclusions is drawn based on the results.The name cone calorimeter was coined from the skeleton of truncated conical vexer that was developed by Dr. Vytenis Babrauskas who used the equipment to irradiate a test archetype of size 100 mm by 100mm. most of the laboratory contain the FTT cone calorimeter as it is covenant 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 criterion.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 sta rting the test. The shutter system also prevents immature ignition of highly ignitable materials(Source Johan, A. 2002. Cone Calorimeter A Tool for Measuring Heat Release Rate. Finland aborigine 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 byThe main objectives for conducting this experiment are to root the rate of heat
