Unit analysis

Material Balance Constraint There are two types of constraints for the unit. These are the process constraints and the equipment constraints. In each of these, there are equahty constraints such as material balances and inequality constraints sucti as temperature limits. Analysts must understand the process and equipment constraints as part of the preparation for the unit analysis. 

Other Process Constraints Typical of these constraints are composition requirements, process temperature limits, desired recoveries, and yields. These are frequently the focus of operators. Violation of these constraints and an inability to set operating conditions that meet these constraints are frequently the motivation for the unit analysis. 

Preliminary models are required to identify significant measurements and the complexity of model required and to test the analysis methods that will be used during the unit analysis. Effort must be devoted during the preparation stage to develop these preliminaiy models. 

The procedure for estimating the potential loss that would follow an incident is set out in Table 9.5 the Unit analysis summary. 

The unit analysis method of problem solving is extremely versatile. You can use it to convert between units or to solve some formula problems. If you forget a formula during a test, you may still be able to solve the problem using unit analysis. 

The unit analysis method involves analyzing the units and setting up conversion factors. You match and arrange the units so that they divide out to give the desired unit in the answer. Then you multiply and divide the numbers that correspond to the units.

The description of stereoisomers is related to analysis in terms of the four-point figures discussed in the previous section. However, these units are seldom encountered unobscured. More common are certain partially overlapping combinations (see Table 1), stereogenic units, analysis of which is an important problem. A stereogenic unit consists of a core of bonds and ligands. 

Compare the results of stratified in-process dosage unit analysis with uniform content of the finished dosage units from the previous step. This analysis should be done without weight correction.

Dimensional analysis is also known as unit analysis or the factor label method. 

Equipment variability assumes an appraiser (color technician) takes a part (final test piece) and measures that part two to three times using a gage (spectrophotometer). Appraiser variability is comprised of two to three appraisers doing the same thing for the same parts. This process is repeated for an additional 1-9 parts. Color values for the 2-10 parts are then entered into a measurement unit analysis form (Tables 26.1 and 26.2).
