Infinitives capitalization

The minimum electrical energy requirement for an electrochemical reactor occurs when the reaction proceeds at an infinitely slow rate. The cell voltage then corresponds to the sum of the anodic and cathodic equilibrium potentials if the reaction is reversible and to the rest potentials if not. Unfortunately, this situation requires an infinite capital investment, so reactions have to be driven at reasonable rates. The reactor or cell voltage is what will achieve the desired rate it must therefore overcome all cell resistances, electrodic and ohmic. As we have seen in Chapter 1, is ... [Pg.52]

In this case, the lives of the machines are unequal, and the comparison is conveniently made on the basis of capitalized cost. This puts lives on the same basis, which is an infinite number of years. The net annual cash flows generated by each machine are equal. [Pg.816]

Secondly, the minimum amount of intermediate storage is determined with and without the PIS operational philosophy. In both cases the production goal was set to that which was achieved when the model was solved with infinite intermediate storage. In the illustrative example a 20% reduction in the amount of intermediate storage is achieved. The design model is an MINLP model due to the non-linear capital cost objective function. This model is applied to an illustrative problem and results in the flowsheet as well as determining the capacities of the required units. [Pg.60]

Whereas it does not make the slightest difference to the individual capitalist whether he produces machinery, sugar, artificial manure or a progressive newspaper - provided only that he can find a buyer for his commodity so that he can get back his capital plus surplus value - it matters infinitely to the total capitalist that his total product should have a definite use-form. By that we mean that it must provide three essentials the means of production to renew the labour process, simple provisions for the maintenance of the workers, and provisions of higher quality and luxury goods for the preservation of the total capitalist himself. [Pg.70]

From a technical point of view it was infinitely easier to plough up large units of land without regard for individual claims than it was to identify each family allotment, measure its value in the peasants traditional terms, and then painfully transpose it from scattered strips into a consolidated farm. Then, too, a capital city administrator could not help but prefer to supervise and tax large productive units and not have to deal with separate farmers.. . . The collective had a dual appeal to authentic agrarian reformers. They represented a social ideal for rhetorical purposes, and at the same time they seemed to simplify the technical problems of land reform and state control. ... [Pg.208]

There are an infinite nvunber of values of ln(z) because arg(z) can differ by multiples of In. The principal mine of ln(z) is defined for the principal value of arg(z), both designated by initial capital letters. Thus,... [Pg.22]

Here, T is the final temperature of the cold product as shown in Fig. 8.9. The cold and hot pinch temperatures represent the temperatures on the cold and hot sides of a heat exchanger where the composite curves are the closest. If the condition in Eq. 8.7 is not true, then it means there is a temperature cross (or internal pinching) within the heat exchanger as shown in Fig. 8.10. When this occurs, the heat exchanger area (or capital cost) becomes infinite. Hence, Eq. 8.7 ensures a finite, positive temperature difference between the hot and cold composite curves (or, in other words, both composite curves are not overlapping as shown in Fig. 8.10). [Pg.250]

The reader should also be aware that infinite reflux columns are the smallest attainable columns in terms of column height however, they do require infinitely large internal flows and hence have operating expenses that are infinitely large to ensure continuous vaporization and condensation. This is the one extreme mode of operation, the other mode being minimum reflux which requires an infinitely high column to be built (and therefore have an initial capital investment that is infinitely large), but the smallest internal flows necessary for a desired separation. This is discussed in more detail in Chapter 4. [Pg.39]

In some major public works projects, such as dams, locks, or bridges, the life of the investment is considered to be infinite. In the case of an infinite life asset, the amount needed to construct or acquire that asset initially plus the amount to provide for the perpetual maintenance and replacement of that asset is referred to as the capitalized cost. A perpetuity is a uniform series of payments that continues indefinitely, such as one would find from the conversion of a capitalized cost to an annuity. [Pg.2350]

In order to quantify the uncertainties in a project it is necessary to indicate the relative chances that a variable (e.g. selling price) will have different values. This can be done subjectively on the basis of, say, a 10% chance that the price will be as low as x, a 10% chance that the price will be as high as z against an expected mid-value of y. If it is assumed that the variables lie in a normal distribution in the range considered then the subjective probability estimates can be used to define the total distribution. Having made estimates of subjective probability distribution for each of the major variables we need a method of combining the various inputs to the project cash flows to obtain the resulting distribution of NPV or DCF, One such method is the Monte Carlo simulation. If there are a number of independent inputs to the project (capital, materials costs, etc) each represented by a probability distribution of values, then there is an infinite number of possible outcomes. Representatives of these... [Pg.148]

Capital investment is the installed costs of the column, its internals, the condenser, and the reboiler. Production costs are the cost of cooling water, steam, and losses of material due to imperfect separation. R can vary from a minimum to infinity. Capital investment is infinite and production... [Pg.278]

Facilities available or underutilized. This is considered the least effective reason for manufacturing choice, but it regrettably seems to be the most prevalent. The history of the composite manufacturing business has been that an independent composite manufacturer would never be expected to reject a contract because of the lack of the optimum facilities or experienced personnel. The independent contractor would find a way to build it or would, in turn, subcontract. The same comment can be extended to most larger companies, such as the large aerospace manufacturers with adequate, but not infinite, facilities in house. Usually, the capital cost and overhead rate of a particular machine will be a strong consideration in the choosing process manufacturers do not want to see valuable machinery idle. [Pg.270]

A second point concerns the solvent flow rates to be used. Low amounts of solvent carry the advantage of low solvent inventory but lead to greater scrubber heights, which in the limit of the minimum flow rate leads to an infinitely high tower. If, on the other hand, we allow an unbounded increase in solvent flow, column height and cost will be reduced to a minimum but operating costs will go to infinity. Between these two extremes there must be an optimmn flow rate that will minimize the total expenditures composed of capital and operating costs. [Pg.390]
