Thermite Background: Thermite is a powder made from aluminum powder and a metal oxide [usually iron oxide (Fe2O3‚ known as rust)]. The thermite reaction is a redox reaction‚ where Aluminum reduces the oxide of another metal. For example‚ when using iron oxide (as I did) the equation would be Fe2O3(s) + 2 Al(s) -> Al2O3(s) + 2 Fe(l). Black or blue iron oxide (Fe3O4) could also be used. Other examples of possible oxides are manganese thermite (MnO2)‚ Cr2O3‚ and copper thermite (CuO). Aluminum can

Ihtisham-ul-haq Gillani Universiti Teknologi PETRONAS Bandar Seri Iskandar 31750 Tronoh Perak Darul Ridzuan ABSTRACT In this new era‚ energy conservation is the main concern. Thermal comfort is the condition of mind that expresses satisfaction with the thermal environment. Unnecessary air condition of heating for thermal comfort is one of the reasons for excessive consumption of energy. Researchers have come up with ways to measure the comfort level in order to avoid over consumption of energy used

Thermal hydraulics analysis of supercritical water reactor core design Jianguo Zhong‚ Michael Podowski Abstract: This paper started with a literature survey of development the supercritical flow reactor core design‚ various coolant flow path designs were discussed: conventional one-pass flow arrangement‚ two-pass and the three-pass coolant flow geometry. A simple 1-D model was developed for the one-pass and two-pass flow design to find the maximum flow bulk temperature and case temperature in

Inkjet Printers Inkjet Printers Inkjet printers are non-impact printers which print text and images by spraying tiny droplets of liquid ink onto paper. They are the most popular printers for home use. Currently‚ most inkjet printers use either thermal inkjet or piezoelectric inkjet technology. Thermal inkjet printer uses heating element to heat liquid ink to form vapor bubble‚ which forces

What is output? Output: is data that has been processed into a useful form. The form of output varies depending on the hardware and software being used and the requirements of the user. There are four basic forms of output: 1. Text 2. Graphics 3. Audio 4. Video A webpage includes more than one of these types of output.

of these reactions may also evolve gases at high rates‚ and could cause reactor over-pressure. Thermal runaway reaction Runaway reactions are thermally unstable reactions where the heat of reaction can raise the temperature of the reactants sufficiently to accelerate the reaction rate out of control. The temperature at which the runaway starts is often termed the onset temperature. A reaction thermal runaway begins when the heat produced by the reaction exceeds the heat removed. The temperature

Other than the monitor‚ we also have the printer which is also an output device. A printer generally translates information that has been processed by the system unit and presents the information on paper. As students‚ we really benefit from such device for in times of projects‚ reports‚ and assignments we greatly rely on such output which we refer to as hard copy. There are five features of a printer ---- its resolution‚ color‚ speed‚ memory and duplex printing. Resolution is the measure of the

Obviously‚ I would have remembered thermal paper but times sure have changed. Thermal fax machines were ones with long roll of paper and each fax would be cut to the size that it transmitted. Plain paper faxes now have saturated the market and the prices have dropped so that anyone
