Industrial data graphical

To interpret sieve data, graphical and statistical methods of data presentation are used. The distribution curve that is widely used in industrial practice was developed by Rosin, Rammler, Sperling, and Bennett in the 1930s (Rosin, Rammler, Sperling, 1997 Rosin and Rammler, 1933 Bennett, 1936). They found out that the size distribution of coal dust and of other crushed and milled materials like cement follows a probability curve with a similar pattern as well-known physical functions such as the Maxwdl-BoUzmann distribution (Section 3.1.4) of the speed of gas molecules (Schubert and Waechtler, 1969). The so-called Rosin-Rammler-Sperling-Bennett (RRSB) function is given by ... 

Generalized charts are appHcable to a wide range of industrially important chemicals. Properties for which charts are available include all thermodynamic properties, eg, enthalpy, entropy, Gibbs energy and PVT data, compressibiUty factors, Hquid densities, fugacity coefficients, surface tensions, diffusivities, transport properties, and rate constants for chemical reactions. Charts and tables of compressibiHty factors vs reduced pressure and reduced temperature have been produced. Data is available in both tabular and graphical form (61—72). 

Five percent random error was added to the error-free dataset to make the simulation more realistic. Data for kinetic analysis are presented in Table 6.4.3 (Berty 1989), and were given to the participants to develop a kinetic model for design purposes. For a more practical comparison, participants were asked to simulate the performance of a well defined shell and tube reactor of industrial size at well defined process conditions. Participants came from 8 countries and a total of 19 working groups. Some submitted more than one model. The explicit models are listed in loc.cit. and here only those results that can be graphically presented are given. 

In this sub-Section a concise overview will be presented of safety indicators commonly used in current chemical process industry. Safety Indicators in this Chapter are restricted to the safety related risk indicators present in an organization. The Sis defined here are present in the chemical process industry in the form of operational data, and in the form of results from (safety) tools. In both cases the Sis aim to indicate the safety status, or risks, Marono (Marono et al., 1998). To retrieve the risk coverage area of commonly used Sis, both the tools, as well as the data they are based on have to be known. The relations between data, tools, and indicators are depicted graphically in Figure 10. 

The examples that have been utilized for determining both EDJ0 (in Chapter 6) and LD50 values in this chapter have been based upon visual inspection of graphical data. In actuality, in the pharmaceutical industry acute LDJ0 as well as EDJ0 values are obtained by employing one or more of several statistical formulas/methods (e.g., Litchfield and Wilcoxon). These analyses provide a more accurate determination of the value in question. 

Figures 5.2-5.6 give only a hint of the spectrum of tools of statistical graphics that are potentially helpful in data analysis for industrial chemistry. For more details and much additional reading on the subject of modern statistical graphics, the reader is referred to the book by Chambers et al.2 listed in the references section.

A large amount of cost data is presented in tabular and graphical form. The table of contents for the book lists chapters where equipment cost data are presented, and additional cost information on specific items of equipment or operating factors can be located by reference to the subject index. To simplify use of the extensive cost data given in this book, all cost figures are referenced to the all-industry Marshall and Swift cost index of 904 applicable for January 1, 1990. Because exact prices can be obtained only by direct quotations from manufacturers, caution should be exercised in the use of the data for other than approximate cost-estimation purposes. 

The increased use of the Internet in recent years as a means of communicating information on drugs and medical devices has provided considerable benefits to the healthcare industry. The Internet offers many possibilities in terms of graphic representation of data and the ability to publish information to a wider audience at a faster speed than by the use of traditional marketing channels. The overriding compliance consideration, however, is the accurate transmission of information to the reader, whether the reader is a member of the public or a pharmaceutical or healthcare professional.
