TGOR – total gas oil ratio (GOR uncorrected for gas lift gas present in the production fluid [citation needed]) TH – tubing hanger; THCP – tubing hanger crown plug; Thr/Th# – thruster ('#'- means identification letter/number of the equipment, e.g. thr3 or thr#3 means "thruster no. 3" [citation needed]) THD – tubing head; THERM ...
W n / n = (1 − α) 2 α n−1. where W n is the weight fraction of hydrocarbons containing n carbon atoms, and α is the chain growth probability or the probability that a molecule will continue reacting to form a longer chain. In general, α is largely determined by the catalyst and the specific process conditions.
The Bosch reaction is a catalytic chemical reaction between carbon dioxide (CO 2) and hydrogen (H 2) that produces elemental carbon (C,graphite), water, and a 10% return of invested heat. CO 2 is usually reduced by H 2 to carbon in presence of a catalyst (e.g. iron (Fe)) and requires a temperature level of 530–730 °C (986–1,346 °F).
Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt.% or % w/w; see mass versus weight). It is one way of expressing the composition of a mixture in a dimensionless size ; mole fraction (percentage by moles , mol%) and volume fraction ...
This is a simplified and more modern variant of L-Jetronic. The ECU was much cheaper to produce due to more modern components, and was more standardised than the L-Jetronic ECUs. As per L-Jetronic, a vane-type airflow sensor is used. [4] Compared with L-Jetronic, the fuel injectors used by LE-Jetronic have a higher impedance. [5]
f: finish: An italic f (Latin small letter f) written on a line representing a surface was an old way of indicating that the surface was to be machined rather than left in the as-cast or as-forged state. The "f" came from "finish" in the sense of "machine finish" as opposed to raw stock/casting/forging.

Dimensionless numbers (or characteristic numbers) have an important role in analyzing the behavior of fluids and their flow as well as in other transport phenomena. [1] They include the Reynolds and the Mach numbers, which describe as ratios the relative magnitude of fluid and physical system characteristics, such as density, viscosity, speed of sound, and flow speed.
