Something is missing

The incidents listed earlier in this chapter and many others could have been foreseen if the design had been subjected to a hazard and operability study (hazop). This technique allows people to let their imaginations go free and think of all possible ways in which hazards or operating problems might arise. But to reduce the chance that something is missed. 

Thermal-property data are needed to relate the enthalpies to temperatures. We would then have 10 variables Q, F, V, W ,T, V , p, T , P, and Counting Eqs. (3.35) and (3.40) to (3.46) we see there are only nine equations. Something is missing. A moment s refleetion should generate the other relationship, a physieal eonstraint Ij, +1 = total volume of tank. 

Now, what is the value of the line ((null /)...) There is no value something is missing. 

At first glance, the job specifics listed in Exhibit 8-1 may seem obvious to you, but do yourself a favor and double-check with your contact at the company. Company protocol often dictates that you receive an offer letter, stating the conditions of your employment. If something is missing from the letter, especially something that was promised orally, ask that you receive a new letter or addendum. 

It is reckoned that there is a lack of communication here something is missing in translation between the engineer and the microbiologist, and between the researcher and the engineer. Schematically, this Tower of Babel can be shown as in Figure 4.52. 

If eqs. 14.5 through 14.8 told the whole story, all polymers formed by free-radical chain growth would be linear. But we know from physical measurements that many such polymers have branched chains, so something is missing from the scheme.
