White phosphorus is used in smoke, illumination, and incendiary munitions, and is commonly the burning element of tracer ammunition. [1] Other common names for white phosphorus munitions include WP and the slang terms Willie Pete and Willie Peter, which are derived from William Peter, the World War II phonetic alphabet rendering of the letters ...
Scalding is a form of thermal burn resulting from heated fluids such as boiling water or steam. Most scalds are considered first- or second-degree burns, but third-degree burns can result, especially with prolonged contact. The term is from the Latin word calidus, meaning hot. [1]
Burn-in is the process by which components of a system are exercised before being placed in service (and often, before the system being completely assembled from those components). This testing process will force certain failures to occur under supervised conditions so an understanding of load capacity of the product can be established.
A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.
The constant volume adiabatic flame temperature is the temperature that results from a complete combustion process that occurs without any work, heat transfer or changes in kinetic or potential energy. Its temperature is higher than in the constant pressure process because no energy is utilized to change the volume of the system (i.e., generate ...
On the other hand, an instant hot water dispenser without a tank does not waste significant energy. When hot water is needed, the instant heater consumes at least 2000 watts to produce hot water at 92 °C and above. [citation needed] The hot water flow rate is approximately 20 litres per hour. Comparing this with the insulated tank type of hot ...
* And when keeping food warm or letting it sit out at room temperature, always keep in mind the cooking "danger zone," of which few home cooks are aware. Food should never stay between 41-135 ...
In fishkeeping, a refugium is an appendage to a marine, brackish, or freshwater fish tank that shares the same water supply. It is a separate sump , connected to the main show tank. [ 1 ] It is a " refugium " in the sense that it permits organisms to be maintained that would not survive in the main system, whether food animals, anaerobic ...
