The first stage toward producing an accurate estimate is to use a standard cost code for all construction projects. Table 9-45 shows a suitable numerical cost code, and Table 9-46 shows a typical alphabetical-numerical code. The cost-code system can be used throughout the estimating and construction stages for the collection of cost data by manual or computer methods. There are numerous types of fixed-capital-cost estimates, but in 1958 the American Association of Cost Engineers defined five types as follows ... 

If the mixing is "perfect," tlie estuary behavior may be approximated by what chemical engineers define as a continuous stirred tank reactor (CSTR) (5). However, accurately estimating the time and spatial beliavior of water quality in estuaries is complicated by the effects of tidal motion as just described. The upstream and downstream currents produce substantial variations of water quality at certain points in the estuary, and tlie calculation of such variation is indeed a complicated problem. How ei er, the following simplifications provide some reiiitirkably useful results in estimating the distribution of estuarine water quality.

To start the process, the engineer defines as accurately as possible the inputs, outputs and energy and cost objective functions. Then the reference environments, both physical and economical are defined. These are not necessarily straightforward steps, as for example when dealing with high rates of... 

Engineers define interest as the compensation paid for the use of borrowed capital This definition permits distinction between profit and interest. The rate at which interest will be paid is usually fixed at the time the capital is borrowed, and a guarantee is made to return the capital at some set time in the future or on an agreed-upon pay-off schedule.

Chemical engineers define the internal porosity, p, as the volume fraction of the particles that is available to the mobile phase. Thus, we have... 

Capital cost estimation is an essential part of investment appraisal. Many types of capital cost estimates are made, ranging from the order of magnitude to detailed estimates requiring the collection of accurate technical data. The American Association of Cost Engineers defined five types of cost estimates as follows ... 

How do engineers define energy and work differently from chemists Why do engineers take this approach ... 

In aircraft calculations the drag coefficient of a wing usually is based on the wing s horizontal surface rather than on the area perpendicular to the flow. In addition, aeronautical engineers define a lift coefficient Q with exactly the same form as EqJ 6.53. In the equation F stands for the upward force of the air exerted on an airplane s wings, A stands for the horizontal wing surface, and Cj is replaced with C,.

Engineers also use the term slope, but they use a mathematical calculation to define it. Engineers define slope as the rise (the upward distance) over the run (the horizontal distance).
