Analysis (or Material and Energy Balances, as it is frequently called at otherschools) class simultaneously, they generally begin the semester with little or nounderstanding of basic chemical engineering concepts. Thus, in addition to learning the“nuts and bolts” of using the simulation packages, they also must learn at least therudiments of such common unit operations as heat exchangers, reactors, flash drums, anddistillation columns. Of course, at this level the students are asked to accept some of theinformation (such as the governing equations) “on faith”, with the promise that the detailswill be covered in subsequent chemical engineering classes such as Heat Transfer,Kinetics, Chemical Engineering Thermodynamics, and Mass Transfer.

The class is askedto show an overall material and energy balance for the automobile and the scientificprinciples that are involved in an automobile process. After some discussion, the class isshown an overall process and a process flow sheet of the various process units which are apart of the overall process of the automobile with the following unit processes:• The flow of fuel and air, the ignition, combustion reactions and the exhaust of combustion products to the atmosphere,• The heat transfer process in cooling the engine,• The

synthetic vs. a biologicalroute. The students can explore both options and design a system to accomplish the goal, thencompare yields, mass balances, etc. at the preliminary level to get them thinking about the issues,similarities, energy balances and costs, etc.Second YearWe propose to modify the second year sequences by replacing the Physical Chemistry withOrganic chemistry, and requiring that the advanced chemistry elective in the spring bebiochemistry . Physical Chemistry will be delayed until the Junior year. The courses coveringThermodynamics and Process Calculations (CBE 10,11) will be modified in content. Thetraditional first course is devoted to steady-state material and energy balances, withthermodynamics providing the background for

The kits contained a variety of tanks, pumps, piping,fittings and sensors. The main pieces have quick release fittings allowing a process, includingsensors and control valves, to be assembled quickly and easily. Students connected the sensorsand

transfer inthe human body.The learning objectives of this hands-on experiment are (1) to analyze chemical reactions thatproduce energy from food (2) to perform material and energy balances on the body, (3) toprepare a simple process flow diagram, and (4) to use a process simulator to investigate rates ofheat transfer during respiration. Students use their own gas exchange respiration data tocalculate their rate of energy expenditure and mechanical efficiency during cycling. They usereaction stoichiometry to determine the quantities of fats and carbohydrates that are used asenergy sources. They apply energy balances to determine the rate of heat transfer throughrespiration, and compare this to the total energy expenditure. Finally, students create
