Jet fuel burns at temperatures between 800 to 1500 degrees Fahrenheit. Designed specifically for use with gas-turbine engines, jet fuel is available in three varieties: Jet A, Jet A-1 and Jet B. The latter is used for improved cold-weather performance.Continue Reading
The flash point of both Jet A and Jet A-1, the two most commonly used fuels for commercial aviation, is 100 F. They both have an autoignition temperature of 473 F.
Jet A is usually found only in the United States, and the rest of the world uses Jet A-1. The main difference between the two jet fuels is that A-1 freezes at a lower temperature. They are both kerosene-type jet fuels.
Consumption of jet fuel worldwide has tripled from close to two million barrels a day in 1980 to more than five million barrels per day in 2010. Efforts are being made to develop alternatives including synthetic jet fuels and jet biofuels. Qatar Airways used a 50:50 blend of synthetic jet fuel and conventional jet fuel successfully for a 6-hour flight in 2009.
Jet fuel is used in some vehicles with diesel engines because of its similarity to diesel fuel. A few engine manufacturers also produce aircraft diesel engines which can run on jet fuel.Learn more about Airplanes & Helicopters
Jet engines propel airplanes forward by sucking in air at the front of the turbine, compressing the air to raise its pressure, spraying the pressurized air with fuel and igniting it. The resulting explosion is forced out the nozzle in the back of the engine, producing considerable forward force.Full Answer >
The temperature in Jupiter's core can reach temperatures of 43,000 degrees Fahrenheit, while the temperature of the planets clouds can plunge as low as -234 degrees Fahrenheit. The extreme temperatures experienced in Jupiter's core are actually hotter than the sun's surface, which is 10,000 degrees Fahrenheit in comparison.Full Answer >
The rate of which frostbite occurs will depend on the temperature and the wind speed; however, in temperatures that are considered to be extremely cold, which depending on these two factors can be anywhere from -32 to -72 degrees Fahrenheit, exposed skin is vulnerable to frostbite after approximately 10 minutes and in temperatures that are considered to be frigidly cold, which is anywhere from -48 to -98 F with higher wind speeds, exposed skin can become frostbitten in as little as 5 minutes, as reported by the National Weather Service. Wind chill is dependent on the temperature and the wind speeds, and quicker wind speeds can help accelerate the rate of frostbite.Full Answer >
Most refrigerators have adjustable temperatures, and experts recommend setting the temperature between 35 and 38 degrees Fahrenheit. Setting the temperature higher than this can lead to premature spoiling and potentially dangerous bacterial growth, and setting it lower can cause some food to freeze in cold spots.Full Answer >
