FOR questions

For question 7, if heat recovery equipment were installed to raise the incoming ctfluent to 425°C, how much natural gas would have to be burned per hour ... 

For question 13, what types of testing would you recommend to ensure uniformity of waste batches that enter the treatment facility to minimize violent exothermic reactions from occurring between waste treatments ... 

Go to the Web and develop a list of suppliers along with unit costs for some of the various types of flocculants described in this chapter. Also obtain the MSDS (Material Safety Data Sheets) for these chemicals. Once you have collected the information, develop a relative ranking of unit cost and health risk associated with each. For question 2 you will need information of recommended doses. 

For question 14, how much will the washing time change if the filtrate viscosity is double and the viscosity of the wash water is 1 cP ... 

Figure for Question 2. Plot of Reynolds number, and settling number (Lyashenko number) versus Archimedes number. Use this plot for question 3. It also useful for your own design problems. 

Take the results for questions 4 and 5 and do a comparative cost analysis. First go the the Web and find suitable equipment suppliers that will provide the equipment in the size ranges you have calculated. Obtain some vendor quotes (rough ones will do). Then perform the fowllowing analysis (a) What are the comparative costs between the two oprions for energy use (b) What are the comparative costs between the two options in terms of maintanance and labor costs (c) Can you combine both equipment options into a single process, and if so, can you justify this and how Assume in the above that the reduction in solids concentration must meet the 1 % weirht criteria described in question 4. 

For question 9, the municipal landfill has had public relations problems with the community. There has been concern over both odor issues and possible groundwater contamination. Taking these concerns into consideration, can you develop addional arguments that make the investment more finacially attractive ... 

Before trying to solve the master equation for growth processes by direct stochastic simulation it is usually advisable to first try some analytical approximation. The mean-field approximation often gives very good results for questions of first-order phase transitions, and at least it provides a qualitative understanding for the interplay of the various model parameters. 

The PSM champion has decided to devote the first hour to a structured presentation, using the balance of available time for questions and answers. 

Follow the directions for Question 19 for the following pairs of solutions. 

Follow the directions for Question 9 for the complex ions in Question 6. 

Follow die directions for Question 7 for a salt bridge cell in which die anode is a platinum rod immersed in an aqueous solution of sodium iodide containing solid iodine crystals. The cathode is another platinum rod immersed in an aqueous solution of sodium bromide with bromine liquid. 

In Spite of the existence of numerous experimental and theoretical investigations, a number of principal problems related to micro-fluid hydrodynamics are not well-studied. There are contradictory data on the drag in micro-channels, transition from laminar to turbulent flow, etc. That leads to difficulties in understanding the essence of this phenomenon and is a basis for questionable discoveries of special microeffects (Duncan and Peterson 1994 Ho and Tai 1998 Plam 2000 Herwig 2000 Herwig and Hausner 2003 Gad-el-Hak 2003). The latter were revealed by comparison of experimental data with predictions of a conventional theory based on the Navier-Stokes equations. The discrepancy between these data was interpreted as a display of new effects of flow in micro-channels. It should be noted that actual conditions of several experiments were often not identical to conditions that were used in the theoretical models. For this reason, the analysis of sources of disparity between the theory and experiment is of significance. 

Is the mean Xmean significant The answer is the same as for question (1), but with /i = 0. If the values (Xmean -2-5 ) and (Xmean + 2-5 ) bracket zero, it is improbable that p differs from zero. 

If Ho holds for question 1, all authors agree that a f-test can be performed. If Hi is true, opinions diverge as to the propriety of such a f-test. In practice, a f-test will be performed If the outcome is clear, that is f is much different from tc, fhe differences between the models are negligible if f is close to tc, more tests should be performed to tighten the confidence limits, or judgment should be suspended until other evidence becomes available. 

Of these sources, Kirk-Othmer s Encyclopedia of Chemical Technology is particularly recommended for questions on chemistry and on end uses. For information on properties and on toxicity and handling hazards, Patty s Industrial Hygiene, Material Safety Data Sheets (MSDS), and the Aldrich catalog are very nseful. Questions on industrial chemistry should be directed to Ullman s Encyclopedia of Industrial Chemistry, and the texts by Chenier, Heaton, and White. Hawley s Condensed Chemical Dictionary is valuable as a source for dehnitions of the terms (language) of chemistry. 

Each presentation is allotted a maximum of 30 minutes and an additional 5 minutes for questions and answers. 

In 1945 Von Schnitzler had said absolutely nothing significant while Dr. ter Meer was around. Whenever Ter Meer landed in the same jail with him, he stopped talking. Ter Meer was now at Dachau, and he was slated to come back to Numberg for questioning within a few days. 

For each precursor, one or more control elements turned out to be ineffective. This justifies the remark that this study gives no rise for questioning the completeness of the control model. 

The percentage after each major topic indicates the approximate proportion of questions on the examination that pertain to the specific topic. The examination is constructed using the percentages as guidelines for question distribution. 

Directions The first lettered list consists of the answer choices for questions 1-5, the second list gives the answer choices for questions 6-10, and the third list gives the answer choices for questions 11-14. Select the letter of the one choice that properly identifies the given compound (questions 1-5), describes the given reaction (questions 6-10), or identifies the product of the reaction (questions 11-14). A choice may be used once, more than once, or not at all in each set. 

Loss of belief in science is the result of media reports of contradictory research by scientists on a wide range of (mainly health) issues and a belief that science was often used for questionable ends (cloning, developing drugs for profit, and others). Trust in medicine is diminishing following media coverage of mistakes and bad practice by doctors. These concerns influence perceptions of food and food safety if scientists and medical researchers cannot all be trusted, this undermines the information and opinions they provide about food. 

Does any industrial water-gas shift catalyst exist that can reach equilibrium CO conversion at 410 K for Question 3 a ... 

A scale of two to nine gradations is usually used for questions (1) and (2), although five or so gradations are probably most common. A typical five-point scale for question (2) would be that the patient is rated as 1 (much worse), 2 (minimally worse), 3 (unchanged), 4 (minimally improved), or 5 (markedly improved). 

Co-catalysts other than water. Trichloro- and monochloro-acetic acids, when used as cocatalysts, induced instantaneous polymerisation at -140°. With the following co-catalysts the rate of polymerisation at -78° decreased in the order acetic acid > nitroethane > nitromethane > phenol > water [75a]. Since this is also the sequence of the acid dissociation constants of these substances in water, it appears that the catalytic activity , as shown by the rate of polymerisation, is correlated with the acidity of the cocatalyst in aqueous solution. Flowever, there are two reasons for questioning the validity of this correlation.
