Unreferenced auto yes date December 2009 A fraction in chemistry is a quantity collected from a sample or batch of a substance in a fractionation fractionating separation process . In such a process, a mixture is separated into fractions, which have compositions that vary according to a gradient. A fraction can be defined as a group of chemicals that have similar boiling point s. A common fractionating process is fractional distillation . It is used to produce liquor and various hydrocarbon fuels, such as gasoline , kerosene and Diesel fuel diesel . A fraction is the product of a fractionating column . A vast chamber designed to separate different substances based on their boiling point, e.g. crude oil . Fraction may also refer to a description of the composition of a mixture, e.g. mass fraction chemistry mass fraction or mole fraction .

Unreferenced date March 2009 Astrodynamics navbar In aerospace engineering , payload fraction is a common term used to characterize the efficiency of a particular design. Payload fraction is calculated by dividing the weight of the payload by the weight of the otherwise empty aircraft when fully fueled. Fuel represents a considerable amount of the overall takeoff weight, and for shorter trips it is quite common to load less fuel in order to carry a lighter load. For this reason the useful load fraction calculates a similar number, but based on the combined weight of the payload and fuel together. Propeller driven airliner s had useful load fractions on the order of 25 35 . Modern jet engine jet powered airliners have considerably higher useful load fractions, on the order of 45 55 . For spacecraft the payload fraction is often less than 1 , while the useful load fraction is perhaps 90 . In this case the useful load fraction is not a useful term, because spacecraft typically can t reach orbit without a full fuel load. For this reason the related term mass fraction , is used instead. However, if the latter is large, the payload can only be small. Examples Mass fraction table Note the above table may incorrectly include the mass of the empty upper stage or stages.

div style float right border solid 10px white Renal worksheet div In renal physiology, the filtration fraction is the ratio of the glomerular filtration rate GFR to the renal plasma flow RPF . Filtration Fraction , FF GFR RPF The filtration fraction, therefore, represents the proportion of the fluid reaching the kidneys which passes into the renal tubules . It is normally about 20 . The GFR on its own is the most common and important measure of renal function. However, in a condition such as renal artery stenosis , the blood flow to the kidneys is reduced. The filtration must therefore be increased in order to perform the normal tasks of the kidney in balancing fluid and electrolytes in the body. This would be reflected by a high filtration fraction, showing that the kidneys have to do more work with the fluid they are receiving. Diuretics such as Loop diuretics loops and thiazides decrease the filtration fraction. Catecholamines Norepinephrine and Epinephrine increase the filtration fraction by vasoconstriction of afferent and efferent arterioles, which is possibly activated by alpha 1 adrenergic receptors.
