Critical lines list

Exhibit 16-1 shows that the first step in the stress analysis work process is to identify the lines on the critical lines list. The critical lines list is a list of line numbers that are likely to receive formal calculations by the stress engineer. This list of lines is important to the designer. It identifies those lines that have the most potential for layout revision requests. The revision requests typically come from the stress engineer on the project. The designer will usually apply the techniques described later to the lines in the critical lines list. [Pg.389]

The stress engineer normally supplies the critical lines list. At times the critical lines list is not available. The designer can then use the following tables as a guideline. There are two tables used for determining the critical lines. Hie designer uses the first table for lines attached to rotating equipment, such as pumps. [Pg.389]

CO -benzene, and CO -n-decane. The critical densities and the corresponding compositions are plotted in Figure 1. The three hydrocarbons in order of higher to lower solubility in C0 were heptane, benzene, and decane. The measured binary diffusion coefficients or the decay rates of the order-parameter fluctuations at various temperatures and pressures are listed in Tables I, II, and III for CO -heptane, CO -benzene, and CO -decane systems respectively. In Figure 2, the critical lines of the three binary systems in the dilute hydrocarbon range are shown in the pressure-temperature space. dP/dT along the critical lines of CO.-heptane and CO -benzene systems are similar and lower than dP/dT along the critical line of CO -decane system, which indicates that C02 and decane form more asymmetric mixtures relative to CO with heptane or benzene. [Pg.5]

The first line lists the experimental result the second line- the atomic procrystal p is the electron density V2p is the Laplacian, g, v and he are the kinetic, potential and total electronic energies at the critical point R is the bond path length. [Pg.240]

Figure 15. Left-. Geometry of the surface 6 = 0 in Eq. (46) with fixed total angular momenta S and N. Properties of the special points A, B, C, and D are listed in Table I. All other permissible classical phase points lie on or inside the surface of the rounded tetrahedron. Right. Critical section at J. Continuous lines are energy contours for y = 0.5 and N/S = 4. Dashed lines are tangents to the section at D. Axes correspond to normalized coordinates, /NS and K JiN + S). Taken from Ref. [2] with permission of Elsevier. Figure 15. Left-.

The methods described above were tested at two sites in Hawaii The Nuuanu reservoir on Oahu, which is above downtown Honolulu, and the Waikoloa Dam on Hawaii Island, which is above the town of Waimea. In both cases the analyses were performed with and without topographic data obtained by a field survey crew. Detailed results from the ca e studies and results of a sensitivity analysis are reported elsewhere. The flood inundation maps produced for Waimea and Honolulu were overlaid onto several GIS infrastructure layers. These layers included major roads, secondary roads, schools, nursing homes, hospitals, police stations, fire stations, civil defense headquarters, chemical plants, electric plants and transmission lines, water plants, and wells (which could be contaminated by floodwaters). Critical facilities in the flood zone were identified and listed along with their mailing addresses and phone numbers of contact personnel. [Pg.201]

In the discussion above, conditions described referred to perfect world conditions—that is, to those conditions that we would want (i.e., the security manager s proverbial wish list) to be incorporated into the design and installation of new chemical industry infrastructure. Post-9/11, in a not-so-perfect world, however, many of the peripheral (fence line) measures described above are more difficult to incorporate into chemical industry site infrastructure. This is not to say that industrial chemical facilities do not have fence lines or fences most of them do. These fences are designed to keep vandals, thieves, and trespassers out. The problem is that many of these facilities were constructed several years ago, before urban encroachment literally encircled the sites—allowing, at present, little room for security stand-backs or setbacks to be incorporated into plants or critical equipment locations. Based on personal observation, many of these fences face busy city streets or closely abut structures outside the fence line. The point is that when one sits down to plan a security upgrade, these factors must be taken into account. [Pg.157]

In the line giving the name of the solvent, or just below it, alternative names of the solvent are shown, and also its melting point.if this is higher than some of the CST. Similarly, the critical temperature of the solvent is listed if it is a pertinent factor in the observations. Also listed are references to the supplementary tables. This furnishes an index to them. [Pg.7]

Qualification is the process of establishing appropriately documented verifications and tests that provide a high level of assurance that a computer system will operate in accordance with predefined specifications. The specific approach to be used for each level of qualification should be outlined in the project validation plan and needs to focus on the critical parameters, data, and functionality of the computer system. While there are no absolute lines to be drawn between qualification testing of a computer system, it is recognized that the qualifications listed below provide the necessary control and continuity throughout the validation life cycle and must be approved for the system to be released for use in the GMP environment. [Pg.612]

The hazard identification methods presented in Sections 1.5.1 to 1.5.6 above are all based on strongly systematic procedures. In the check list method, the systematic is provided by the check list itself. The comprehensiveness can be verified in the matrix (see Figures 1.4 and 1.5). With the FMEA, the systematic is provided by the division of the system into elements and the failure modes considered. In the HAZOP study, the systematic stems from the division of the plant into nodes and lines, then the systematic application of the keywords. With the decision table method, the systematic is inherent to the table. For the FTA and ETA, the systematic is given by the tree and the logical ports. Nevertheless, the work of the team must be traceable, even by persons who did not participate to the analysis. Thus, it is recommended to also document the hazards that were not considered as critical. [Pg.28]

Moreover, the troubles for Aristotle s scheme do not end with this list of highest kinds—Kant s criticism extends to Aristodes intra-categorial divisions of quantity and quality as well. Aristode divides each of these categories into several distinct species quantity divides into continuous and discrete quantities, the former of which divides into body, line, surface, time and place, the latter of which divides into... [Pg.4]

In-process tests will appear at critical stages in a process to ensure all is going to plan and that any deviations from the set process can be explained. The SOPs required to support the process will be listed so that they can be made available at the time of use. Since a batch of crude product will be purified in several portions there will be some form of cleaning between operations. This may include anything from washing the solvent lines to a fraction collector through to regeneration of the stationary phase. [Pg.108]

Mobile Phase Properties. Some chemicals that could be used in SFC are listed in Table 2. The one that has been used most commonly is carbon dioxide, and it will be the focus of this short introduction. Figure 11.1 shows the pressure-volume phase diagram for CO2 at various temperatures. The critical values (Pc = 7.4 MPa, Vc = 96 mL, and Tc = 31° C) intersect approximately at the point marked X. Liquid exists in the lined space at the left of the diagram, gas and liquid are in equilibrium in the space cut off by the dashed line, supercritical fluid exists above the critical temperature, and gas exists at the right. Remember that the critical temperature is that temperature above which a gas cannot be liquefied no matter how high the pressure. [Pg.279]
