Characteristic Systems

A compressor discharging into a large system through a long run of pipe would have a system characteristic defined by AO. A system which has essentially fixed top pressure with some pipe friction is represented by AC.

The generation of au pollutants, ineluding VOC s, from automotive vehieles was identified to eome from two prineipal sourees vehiele exhaust emissions, and fuel system evaporative emissions [4], Evaporative emissions are defmed as the automotive fuel vapors generated and released from the vehiele s fuel system due to the interactions of the speeific fuel in use, the fuel system characteristics, and environmental factors. The sources of the evaporative emissions are discussed below and, as presented m the remainder of this chapter, control of these evaporative emissions are the focus of the application of activated carbon technology in automotive systems. 

The economic factors must be considered in every application. It is important to find a technique that will meet both the technical and economical requirements. In short, pollution control costs depend on the system characteristics and the application. Some cost equations that generalize the economics of the managing systems are available in the literature. Most of these equations give rough estimates and have an accuracy of only about 30% to 50%. For a comprehensive cost comparison of different units, a detailed cost analysis based on the equipment tender proposals and the special characteristics of the project is necessary.

IWo basic types of questionnaires can be used yes/no or open-ended. A sample yes/no questionnaire is provided in Figure 4-6 Figure 4-7 displays an open-ended version. The yes/no questionnaire confirms the existence of specific PSM program components or management system characteristics, while an open-ended questionnaire requires an explanation of the response and can be used to invite discussion. Yes/no questionnaires can be filled out by the facility or can be administered by less experienced assessors. Open-ended questionnaires require more experienced assessors, who are equipped to guide discussion and probe for further information. 

The centralized team(s) will approach PSM element by element. The teams develop detailed guidelines, procedures, and standards for each PSM element, which can then installed by facility management. Howevei in handling one PSM element at a time, teams must be careful to incorporate a consistent approach to those elements that are interrelated (e.g., training), and to the management system characteristics (e.g., documentation) that apply to the whole PSM system.

During the last three decades, many hydrothermal deposits have been discovered at midoceanic ridges, back-arc basins and subaerial active geothermal systems. Characteristic features of back-arc deposits at the western Pacific region (e.g., Okinawa Trough, Izu Ogasawara, North Fiji and Mariana deposits) are very similar to those of Kuroko deposits.

All the above changes are easily implementable in dynamic simulations, using ISIM and other digital simulation languages. The forms of response obtained differ in form, depending upon the system characteristics and can be demonstrated in the various ISIM simulation examples. The response characteristics of real systems are, however, more complex. In order to be able to explain such phenomena, it is necessary to first examine the responses of simple systems, using the concept of the simple, step-change disturbance.

Since the system characteristic equation is 1 + GcGp = 0, our closed-loop poles are only dependent on our design parameter xc. A closed-loop system designed on the basis of pole-zero cancellation has drastically different behavior than a system without such cancellation.

Example 7.2 If we have only a proportional controller (i.e., one design parameter) and real negative open-loop poles, the Routh-Hurwitz criterion can be applied to a fairly high order system with ease. For example, for the following closed-loop system characteristic equation ... 

There will be m root loci, matching the order of the characteristic polynomial. We can easily see that when Kc = 0, the poles of the closed-loop system characteristic polynomial (1 + KCG0) are essentially the same as the poles of the open-loop. When Kc approaches infinity, the poles of the closed-loop system are the zeros of the open-loop. These are important mathematical features.

Some general guidelines for the application of the proper valve characteristic are shown in Fig. 10-14. These are rules of thumb and the proper valve can be determined only by a complete analysis of the system in which the valve is to be used [see also Baumann (1991) for simplified guidelines]. We will illustrate how the valve trim characteristic interacts with the pump and system characteristics to affect the flow rate in the system and how to use this information to select the most appropriate valve trim.
