Fig. 4.8 Hydrograph of an observation well at the Saratoga National Historic Park, New York (after Winslow et al., 1965), and local precipitation graph. Interpretation is discussed in the text.

The shapes of the nodes are voluntarily chosen among various polygonal shapes in order to distinguish variables in a Formal Graph. When color is available, a distinctive color comes as a supplementary mark for facilitating graph interpretation. These distinctive features will be explained in the subsequent chapter. 

Archey et al. (Chapter 6) outline a pedagogieal approaeh whieh introduces general chemistry concepts through consideration of environmental issues such as carbon dioxide uptake by the Amazon jungle. Application of concepts such as stoichiometry, molarity, solubility, and graph interpretation to the carbon footprint discussion of global sustainability exemplifies the utility of context-based pedagogy.

Data reduction. The process of transforming the initial digital or analog representation of output from a spectrometer into a form that is amenable to interpretation, e.g., a bar graph, a table of masses versus intensities. 

The right-hand side is now a pure number and, if we wish to plot mass, in grams, against, say, volume on a graph we label the mass axis m/g so that the values marked along the axis are pure numbers. Similarly, if we wish to tabulate a series of masses, we put m/g at the head of a column of what are now pure numbers. The old style of using m(g) is now seen to be incorrect as, algebraically, it could be interpreted only as m x g rather than m g, which we require. 

By using these N,ss values, we ean interpret the Nss Graph, and get a picture of the operating window ofthe.se three pumps. To interpret the graph we start on the left eolumn at the flow in gpm. In Figure 6-15, we draw a line from the flow to the Nss value of the pump, and then reference downward for water, or upward for hydroearbons. 

Consider the following graph. Figure 9-14. Radial loading on the shaft rises if the pump is operated too far to the left or right of the be.st efficiency zone. Another interpretation of the. same concept is to. say that the maintenance and problems rise when the pump is operated away from its BEP. Many pumps have a rather narrow operational window. These pumps can be very efficient if they are correctly specified and operated. This is discussed completely in Chapters 7 and 8 Pump Curves and System Curves. 

In tlie case of a random sample of observations on a continuous random variable assumed to have a so-called nonnal pdf, tlie graph of which is a bellshaped curve, tlie following statements give a more precise interpretation of the sample standard deviation S as a measure of spread or dispersion. 

As an alternative, we might want to plot the square of the wavefunction rather than the wavefunction itself, on the physical grounds that such quantities have a direct interpretation. The form of the graph is very similar to Figure 3.4, and I haven t shown it. 

Pursuing this correspondence between a C-H graph and the corresponding C-graph we find a new interpretation of the numbers p and R p is the number of topologically different free C-trecs with n vertices, R is the number of planted C-trees with n nodes. In other words ... 

Spatial congruence of C-H graphs is applied essentially only in chemical formulas which represent a compound of carbon atoms and atoms of valence 1 (or radicals of valence 1). In this case condition (IV), besides (I), (II), (III), adds another restriction not only the relationships are important but also the spatial arrangement of the bonds. The spatial interpretation of the congruence of C-H graphs coincides with the interpretation of the chemical formula as stereoformula. I use stereoisomers in this sense. For example, the number of different stereoisomers is equal to the number of spati-... 

Rate law and reaction scheme. Interpret quantitatively the data21 presented in the accompanying two graphs in terms of either or both of the sequences that might be considered for experiments in which [Ph2C2] and [CO] [Co2(CO)8]o- The reciprocal of k varies linearly with the reciprocal of the diphenyl acetylene concentration at constant [CO]. The slopes of these double reciprocal plots are directly proportional to [CO]. 

An integral has a further important interpretation the integral of a function evaluated between two points is the area beneath the graph of the function between the two points (Fig. 5). For example, the area beneath the curve y(x) = sin x between x = 0 and x — tt is... 

The solvents themselves are adsorbed on the electrode surface, as is shown by the capacitance-potential graphs illustrated in Fig. 9 (Payne, 1967, 1970) potassium hexafluorophosphate, the electrolyte in each of the solvents, is thought to be adsorbed only very weakly. The solvents show somewhat differing curves and the peaks have been interpreted both in terms of competition between the solvent and anions for sites at the surface and also in terms of solvent reorientation. Ethers are adsorbed from the amide solvents most strongly at the potentials around the peaks and this has been postulated to be due to an increase in freedom for the solvent to rotate at these potentials (Dutkiewicz and Parsons, 1966). 

In any case, what is usually obtained is a graph showing how a concentration varies with time. This must be interpreted to obtain a rate law and a value of k. If a reaction obeys simple first- or seeond-order kinetics, the interpretation is generally not difficult. For example, if the concentration at the start is Aq, the first-order rate... 

The students were also able to explain some of that information by using the symbolic level of representation (the equation that was presented together with the graph). This was observed when they made references to the line on the graph, making clear how they were interpreting it in order to reach their conclusions. 

If the graph y vs. x suggests a certain functional relation, there are often several alternative mathematical formulations that might apply, e.g., y - /x, y = a - - exp(b (x + c))), and y = a-(l- l/(x + b)) choosing one over the others on sparse data may mean faulty interpretation of results later on. An interesting example is presented in Ref. 115 (cf. Section 2,3.1). An important aspect is whether a function lends itself to linearization (see Section 2.3.1), to direct least-squares estimation of the coefficients, or whether iterative techniques need to be used.
