For the world to operate on a unified time platform, it is imperative to have all the major clocks on the globe synchronized to one single accurate/stable clock piloted by the atomic time for precision â master clock. And this is achieved by connecting all clocks to the master clock by a wave called the pilot carrier.
Octane is a hydrocarbon and an alkane with the chemical formula C 8 H 18, and the condensed structural formula CH 3 (CH 2) 6 CH 3. Octane has many structural isomers that differ by the amount and location of branching in the carbon chain. One of these isomers, 2,2,4-trimethylpentane (isooctane) is used as one of the standard values in the octane rating scale. Octane is a component of gasoline (petrol). As with all low molecular weight hydrocarbons, octane is volatile and very flammable.
A by-product of natural gas processing and petroleum refining, it is commonly used as a fuel for engines, oxy-gas torches, portable stoves, and residential central heating. Propane is one of a group of liquefied petroleum gases (LP gases).The others include butane, propylene, butadiene, butylene, isobutylene and mixtures thereof. Propane containing too much propene (also called propylene) is not suited for most vehicle fuels.HD-5 is a specification that establishes a maximum concentration of 5% propene in propane. Propane and other LP gas specifications are established in ASTM D-1835.ropane (/ËproÊpeÉªn/) is a three-carbon alkane with the molecular formula C 3H 8, a gas at standard temperature and pressure, but compressible to a transportable liquid.
