In this table, units of a je and are mixed. To ensure consistency, we convert lA = (0.52) al = 7.1 lag. Also, calculated charge densities refer to fully occupied energy levels, whereas the 1 / ro simulation specifies one-electron densities. The ratio /(1 8) 1.38 compensates for this effect to give the complete conversion factor k = 7.11 x 1.38 = 9.81 that generates the numbers a = m/10 from l/p . From these numbers, polarizabilities are calculated as s = a lro n) = //lO of Table 14. This result provides a simple conversion of calculated dipole moments into Debye units. Noting that... 

Abbreviations are used in the text and in the tables units are omitted in some tables for the sake of conciseness. This necessitates the following clarification ... 

Now scan a range of values of Ar ,in and calculate the targets for energy, number of units, and network area and combine these into a total cost. The results are given in Table 7.4. 

Example 16.1 The process stream data for a heat recovery network problem are given in Table 16.1. A problem table analysis on these data reveals that the minimum hot utility requirement for the process is 15 MW and the minimum cold utility requirement is 26 MW for a minimum allowable temperature diflFerence of 20°C. The analysis also reveals that the pinch is located at a temperature of 120°C for hot streams and 100°C for cold streams. Design a heat exchanger network for maximum energy recovery in the minimum number of units. 

Solution Figure 16.8a shows the hot-end design with the CP table. Above the pinch, adjacent to the pinch, CPfjSCPc- The duty on the units has been maximized according to the tick-oflF heuristic. 

Any change taking place which results in an increase in entropy has a positive entropy change (AS). Most spontaneous thermodynamic processes are accompanied by an increase in entropy. Entropy has units of Joules per degree K per mole. For representative values see table on p. 393. 

The European specifications require a minimum cetane number of 49 for the temperate climatic zones and the French automotive manufacturers require at least 50 in their own specifications. The products distributed in France and Europe are usually in the 48-55 range. Nevertheless, in most Scandinavian countries, the cetane number is lower and can attain 45-46. This situation is taken into account in the specifications for the arctic zone (Table 5.14). In the United States and Canada, the cetane numbers for diesel fuels are most often less than 50. 

Some conversion tables for the different units are used and standardized (ASTM D 2161). 

For example, in the case of light Arabian crude (Table 8.16), the sulfur content of the heavy gasoline, a potential feedstock for a catalytic reforming unit, is of 0.036 weight per cent while the maximum permissible sulfur content for maintaining catalyst service life is 1 ppm. It is therefore necessary to plan for a desulfurization pretreatment unit. Likewise, the sulfur content of the gas oil cut is 1.39% while the finished diesel motor fuel specification has been set for a maximum limit of 0.2% and 0.05% in 1996 (French specifications). 

Table 10.7 shows the typical composition of a feedstock to an etherification unit and the average product properties obtained. 

Reservoir fluids are broadly cafegorised using those properties which are easy to measure in the field, namely oil and gas gravity, and the producing gasioil ratio (GOR) which is the volumetric ratio of the gas produced at standard condition of femperature and pressure (STP) fo fhe oil produced at STP. The commonly used units are shown in the following table. 

The component factor gives the unit yield for each component and includes a volume conversion factor. The factors can be obtained from tables. 

The INTROS MDK-21 consists of an electronic unit and two or three magnetic heads (Fig. 3). Table 1 shows the specification of the magnetic heads. 

Although the processing time unit basically could be further improved table 1 gives some idears what the achieved results and axial resolution mean in several interesting applications and low center frequencies. With low frequencies a lot of attenuation problems available in new engineered materials could be solved. 

The required resolution for the powder coating thickness measurement problem is about 5 microns. Therefore a processing time unit of 0.08 ps (12.5 MHz) seemed to be ok (compare line 2 in table 1). First results based on real measurement are documented in Fig. 7. and are very promising result. Today corresponding patent is pending [7].

One complication is the matter of units while the Systeme International d Unites (SI) requires additional and sometimes awkward constants, its broad use requires attention [1]. Hence, while we present the derivation in the cgs/esu system, we show alternative forms appropriate to the SI system in Tables V-1 and V-2. 

To first order, the dispersion (a-a) interaction is independent of the structure in a condensed medium and should be approximately pairwise additive. Qualitatively, this is because the dispersion interaction results from a small perturbation of electronic motions so that many such perturbations can add without serious mutual interaction. Because of this simplification and its ubiquity in colloid and surface science, dispersion forces have received the most significant attention in the past half-century. The way dispersion forces lead to long-range interactions is discussed in Section VI-3 below. Before we present this discussion, it is useful to recast the key equations in cgs/esu units and SI units in Tables VI-2 and VI-3.
