Engineering is a discipline that teaches andtrains young minds in purification, separation and isolation in a broader sense for processindustries. From an environmental point of view, pollution prevention is the study ofcontaminant purification (P), separation (S) and isolation (I), which we call PSI. These are theunderlying activities that will be used to tackle the contamination problem in its totality. This is aformidable task for a single chemical engineering department in a nation of 130 million people,where meeting the basic necessities of life is by itself a war for existence.However, a solution to these problems is certainly not possible without strong leadership fromthe country’s technical leaders. Toward this end, the expected outcomes of

act with respect to context, or to a string ofcorrelated events. For our purposes, we need an agent that is able to make a judgment based onthe current information it has about what a user has done thus far in a problem situation. This“internal state” defines each step of a proof in the context of what has already been attempted.The basic operation of such an agent is shown in Figure 4. This will be our basic architecture forour first experiments.

D 50 was estimated at 0.041 mm (0.0016in.). Therefore, the design velocity for slurry transport was based on these grain sizes. Durand–Condolios’ limiting deposit velocity equation was used to determine a transition velocity thatseparates the suspended heterogeneous sediments from the moving bed regime. To avoidblockage, the pipeline velocity must be greater than the limiting deposit velocity. The equationis ær ö VLD = FL 2 gD çç S - 1÷÷ Where è rW ø VLD – limiting deposit velocity

IntroductionThe undergraduate engineering education environment is very different from the environment thatthe senior author has experienced. The personal computer has now become ubiquitous and morepowerful than the mainframe computers of the late 70’s and early 80’s while the educationalutilization of the computer has been transformed from writing specific programs in FORTRANfor carrying out calculations for individual problems to mastering specialized applications forsimulations or for data acquisition/processing. With the proliferation of special purposeapplications, undergraduate electrical engineering courses have been enriched with computersimulations with many textbooks
