Watson relation

Tbe enthalpy of vaporization decreases with temperature and is zero at tbe critical point. If tbe value of an enthalpy of vaporization AH is known at temperature T, this temperature dependency can be represented by tbe Watson relation to calculate another enthalpy of vaporization AH at any other temperature To ... 

Interval values for these fundamental properties can be used in equation-oriented estimation techniques. The Watson relation (Watson, 1943)... 

The isobaric specific heat for a petroleum fraction is estimated by a correlation attributed to Watson and Nelson in 1933, which was used again by. Johnson and Grayson in 1961 as well as by Lee and Kesler in 1975. This relation is valid at low pressures i... 

This relation should not be applied for temperatures less than 0°C. Its average accuracy is on the order of 5%. For a Watson factor ot 11.8, the C j can be obtained from the curve shown in Figure 4.4. For different K, values, the following correction is used (... 

The enthalpy of a petroleum fraction is obtained by integration of the Watson and Nelson relations ... 

The incident ions cause recoil in the surface atoms. In studies of ionic liquids, only direct recoil - that is, motion in the forward direction - was measured. Watson and co-workers [56, 57] used time-of-flight analysis with a pulsed ion beam to measure the kinetic energies of the scattered and sputtered ions and therefore determine the masses of the recoiled surface atoms. By relating the measured intensities of the... 

Another relationship used to indicate the crude type is the Watson characterization factor. The factor also relates the mid-boiling point of the crude or a fraction to the specific gravity.

The analyses developed in this section are readily extended to reactions with different stoichiometries. Regardless of whether an adsorption or a desorption process is rate limiting, the resulting rate expressions may be written in the typical Hougen-Watson fashion represented by equation 6.3.30. A comprehensive summary of such relations has been developed by Yang... 

I. Derive equations relating the initial reaction rate (7 0) to the total pressure (71) for each of the above cases when the sulfur dioxide and oxygen are initially present in equimolar amounts. Do this using the Hougen-Watson mechanistic models. Show your derivations. 

In fact, we have talked about the Durbin-Watson statistics in previous chapters, although a long time ago and under a different name. Quite a while ago we published a column titled Alternative Ways to Calculate Standard Deviation [7], One of the alternative ways described was the calculation by Successive Differences. As we shall see, that calculation is very closely related indeed to the Durbin-Watson Statistic. More recently we described this statistic (more directly named) in a sidebar to an article in the American Pharmaceutical Review [8],... 

To relate the Durbin-Watson Statistic to our current concerns, we go back to the basics of statistical analysis and remind ourselves how statisticians think about Statistics. Here we get into the deep thickets of statistical theory and meaning and philosophy. We will try to keep it as simple as possible, though.
