Primary design phase

The above dispersion-optimized single-directional design process repeated along every mesh axis is proven fairly rigorous and convergent, even for coarse lattice resolutions. Hence, spatial derivatives receive an enhanced manipulation without augmenting overall complexity, since (6.42)—(6.46) are computed only once, ahead of the primary simulation phase. 

The PT is the transformer designed to provide the proper voltage to the measuring instruments such as voltmeters, frequency meters, wattmeters, watt-hour meters, etc, as well as protective devices such as relays, in which the secondary voltage is proportional to the primary and phase shift with respect to it an angle dose to zero. 

The requirements for containers originate from the functions protection of the product, facilitate product use and provider of information. In the design phase of the medicinal product the material, form and functions of the primary container are determined. Compatibility of the selected container with the medicinal product is demonstrated by stability studies. 

Various t5q>es of colloidal dispersions occur, as illustrated in Table 1. In practice, many colloidal dispersions are more complex and are characterized by the natin-e of the continuous phase and a primary dispersed phase, according to the designations in Table 1.

The primary justification for this concern is to preclude multiple, independent additions of reactivity to the reactor core at the same time. While modeling efforts may eventually demonstrate that this is not an issue, this precaution should remain until later in the design phase because the reactor s sliders, the Brayton unit speed, and the HRS pump speed are controlled by different portions of the spacecraft. Effective coordination between the control functions on the various segments of the spacecraft needs to be established. 

Heat transfer and mass transfer occur simultaneously whenever a transfer operation involves a change in phase or a chemical reaction. Of these two situations, only the first is considered herein because in reacting systems the complications of chemical reaction mechanisms and pathways are usually primary (see HeaT-EXCHANGETECHNOLOGy). Even in processes involving phase changes, design is frequendy based on the heat-transfer process alone mass transfer is presumed to add no compHcations. But in fact mass transfer effects do influence and can even limit the process rate. 

Tank bottom slope is important because sediment, water, and heavy phases settle at the bottom. Corrosion is usually the most severe at the bottom, and the design of the bottom can have a significant effect on the life of the tank. In addition, if the Hquid stock is changed, it is usually desirable to remove as much as the previous stock as possible. Therefore, designs that allow for the removal of water or stock and the ease of tank cleaning have evolved. In addition, specialized tank bottoms have resulted from the need to monitor and detect leaks. Tank bottoms in contact with the soil or foundations are one of the primary sources of leaks from aboveground tanks. 

For the liquid-phase mass-transfer coefficient /cl, the effects of total system pressure can be ignored for all practical purposes. Thus, when using Kq and /cl for the design of gas absorbers or strippers, the primary pressure effects to consider will be those which affect the equilibrium curves and the values of m. If the pressure changes affect the hydrodynamics, then Icq, and a can all change significantly.
