During the period from ignition to ignition plus the heat release rate reduced from 148.5 kW/m2 to121.3 kW/m2 in 6 minutes, effective heat of combustion increased from 35 MJ/ Kg to 37.6 MJ/ Kg during this period and mass loss rate decreased from 0.043 g/sec to 0.032 g/sec. The specific extinction area reduced from 750.3 m2/kg to 517.3 m2/kg, the carbon monoxide yield reduced from 0.0237 kg/kg to 0.0196 kg/kg and carbon dioxide yield reduced from 2.06 kg/kg to 2.04 kg/kg.
The second blue carpet sample had a slightly lesser mass of 17.63 g with the same surface area and thickness as the first sample. The heat flux of the experiment was increased to 35 kW/m2. The time of the test was only 378 seconds and the total heat evolved was 34.9 MJ/m2. The total amount of oxygen consumed was 24.7 g and the amount of smoke released was 474 m2/m2. The mass lost during the experiment was 13.2 g with a specific mass loss rate of 5.09 g/m2s. During the experiment, the average heat release rate was 103.45 kW/m2 and effective heat of combustion was 20.88 MJ/ Kg. The mass-loss rate was 0.051 g/sec and the specific extinction area was 204.47 m2/kg. During these 6 minutes, the carbon monoxide yield was 0.0149 kg/kg and carbon dioxide yield was 1.21 kg/kg. During the period from ignition to ignition plus the heat release rate reduced from 268 kW/m2 to104.3 kW/m2 in 6 minutes, at the same time, effective heat of combustion increased from 13.7 MJ/ Kg to 20.9 MJ/ Kg and mass loss rate decreased from 0.203 g/sec to 0.051 g/sec. The specific extinction area decreased from 284.3 m2/kg to 204.5 m2/kg in 6 minutes, the carbon monoxide yield increased from 0.0136 kg/kg to 0.0149 kg/kg and carbon dioxide yield increased from 0.90 kg/kg to 1.21 kg/kg. ...Download file to see next pagesRead More

Radiation Experiments

... Radiation Experiments Introduction Ultraviolet rays are a form of electromagnetic waves whose wavelengthis much shorter than that of the visible light. The wavelength varies from 10nm to 400nm, the energy of these wave ranges from 3eV to 124eV. The sun emits UV rays and is one of the natural sources of these rays. Artificially, these rays are produced by backlights, fluorescent lights and electric arcs such as those produced during welding. UV rays have many substantial effects and damages to both living things and the materials. It triggers chemical reactions, causes substances to grow and causes sun burn to people. UV rays are also beneficial to humans; these include the UV watermark that helps in authentication of credit cards...

Psychology (experiments)

...Psychology Submitted: The experiments conducted are regarding the recalling of the list of organized and random words. The words are supplied to the participants in the two forms; audio and visual. In both the cases the participants relied on the organization and clustering of words. The association is also a type of organization and the clustering prevails over association. The organization can be classified into different types and those types can affect the short term memory that will be useful as a retrieval tool for the long term working memory. This depends on the grouping of words according to the system. This is the fundamental step for organization that effects the recalling or retrieving the information. 1.Introduction...

Milgram's Experiments

...As evidenced by Milgram's many experiments, it is virtually impossible that the reason for the German's compliance with Hitler's orders for mass extermination of Jews is that the Germans were "unusually cruel, sadistic people with abnormal and twisted personalities." After World War II, in the Nuremberg War Crimes trials, a common defense of those accused of these crimes against humanity was "obedience.". The prevalence of this justification is what prompted Stanley Milgram to perform his experiments. Milgram's experiments focused on the conflict between obedience to authority and a person's conscience. Milgram recruited participants through newspaper advertisements calling for anyone interested in getting paid for participating...

Cone

... of a material depends upon its chemical composition and the availability of oxygen. Post-fire investigations also need some analytical tool for the forensic investigation to evaluate the extent as well as the cause of damage due to fire. Cone calorimeter is presently considered the best technological tool available for the evaluation and assessment of any material’s reaction to fire. In any physical or chemical reaction if the elements being used up and the products obtained if measured can yield pertinent data about the properties of the substance under study. Cone calorimetry similarly employs the principle of oxygen consumption to determine the net heat of combustion of any organic material. In this experiment, a Cone calorimeter...

Microbiology and Experiments

...Question 1 According to Levin and Feldman (2006) urine culture is the examination of urine sample to find out if there is presence of pathogens responsible for causing Urinary Tract Infection (UTI). This process is necessary if a person experiences sensation when urinating or if there is strong desire to pass urine. Although urine in the bladder is free of pathogens, they may enter through urethra and cause infection. The presence of pathogens in urethra may taint the culture during sample collection process (Levin and Feldman, 2006). Therefore, during this process, it is essential to let some urine to pass before collecting the sample. This will be achieved by pulling off the skin covering penis or vagina with your hand to avoid...

Calorimeter

... for these experiments. The theory of calorimetry is fundamentally used in academic teaching. It is useful in finding the enthalpy change per mole of substance in X in a chemical reaction between two chemicals X and Y. the two substances are placed in a calorimeter and the final and initial temperatures are noted. Multiplication of the change in temperature by mass and the specific heat capacities of the substances in the reaction give the value of energy that is engrossed or given out during the reaction. The method is called the theory of calometry (Kraftmakher, 78). Work Cited Kraftmakher, Yaakov. Modulation Calorimetry: Theory and Applications ; with 27 Tables. Berlin [u.a.: Springer, 2004.
