When the concentration profile is fully developed, the mass-transfer rate becomes independent of the transfer length. Spalding (S20a) has given a theory of turbulent convective transfer based on the hypothesis that profiles of velocity, total (molecular plus eddy) viscosity, and total diffusivity possess a universal character. In that case the transfer rate k + can be written in terms of a single universal function of the transfer length L and fluid properties (expressed as a molecular and a turbulent Schmidt number) ... 

The 850°F+ conversion is a correlating parameter for comparing C1-C4 gas yield, C5-500°F liquid yield, 500°F+ conversion, and 650°F+ conversion. Various combinations of the operating parameters of space velocity, total reactor pressure, and temperature achieve the same 850°F+ conversion. Thus, the product distribution can then be related to 850°F+ conversion with only minor variations between specific experimental runs. No difference in product distribution (at a given 850°F+ conversion) was noted for runs made with SRC-I/prehydrogenated KC-Oil at 70/30 and 50/50 nominal weight ratio feed blends.

Imagine a well isolated space ship observed in an inertial coordinate system. Its energy is preserved, its centre of mass moves along a straight line with constant velocity the total, or centre-of-mass, momentum vector is preserved), it rotates about an axis with an angular velocity total angular momentum preserved ). The same is true for a molecule or atom, but the conservation laws have to be formulated in the language of quantum mechanics.

Maximum x-ray transmission is determined daily by the injection of clear suspending liquid into the spinning disc. The suspension is injected into a stationary disc to determine maximum opacity the disc is then spun at any pre-selected speed between 750 and 6000 rpm and the run started. The nominal run condition is for the source and detector to remain stationary for 1 minute at a radial position of 48mm, reproducible to 4 Llm, and then to scan towards the surface at a constant radial velocity. Total run time is 8 minutes but this, again, is selectable.
