Input Data and Recommended Practices

3.3.5 Input data and recommended practices
J. Taborek
In this section we deal with three subjects:
- The basic set of input data as required for shell-side rating calculations, but also including those required for design of the overall exchanger, that is, including tube-side flow. These are presented in Table 1.
- Detailed comments to the input data, to give guidance to the designer as to proper practices and standards.
- Preliminary calculations of correlational parameters derived from the input data, as required for subsequent calculations.
