About the Material and Energy Balance Spreadsheets Brice Carnahan – University of Michigan Prof. Brice Carnahan at the University of Michigan has assigned a variety of spreadsheeting problems to his students in the first chemical engineering course, Material and Energy Balances. The problems typically involve solution of a class of problems (suitable for solving many related class home problems), although some are more specifically related to a particular situation (e.g., specification of a force-air homeheating furnace and steady-state simulation of a particular methanol-production process). The student problem assignments (in Word .doc files) and Prof. Carnahan’s (in one case student) solutions (in EXCEL .xls files) are included in the folder Carnahan_Mat_Eng_Bal_Sheets as follows: Assignment/Sheet Name Problem Class CoalOilCombustion.doc Assignment: Coal and Liquid Fuel Oil Combustion Stack-Gas Analysis CoalOilCombustion.xls Solution Sheet: Coal and Liquid Fuel Oil Combustion Stack-Gas Analysis FuelCombustion.doc Assignment: Combustion Analyzer for Fuel Mixtures Containing Compounds of Carbon, Hydrogen, and Oxygen FuelCombustion.xls Solution Sheet: Combustion Analyzer for Fuel Mixtures Containing Compounds of Carbon, Hydrogen, and Oxygen GasEnthalpyCp.doc Assignment: Computing Enthalpy Changes and Mean Heat Capacities for Ideal (low pressure) Gas Mixtures GasEnthalpyCp.xls Solution Sheet: Computing Enthalpy Changes and Mean Heat Capacities for Ideal (low pressure) Gas Mixtures MethanolProcessSimulation.doc Assignment: Steady-State Simulation of a Methanol Production Process MethanolBaseCase.xls Solution Sheet: Steady-State Simulation of a Methanol Production Process – Base Case MethanolTestCase.xls Solution Sheet: Steady-State Simulation of a Methanol Production Process – a Test Case OpenSysReactors.doc Assignment: Open-System Chemical Reaction Mass and Energy Balances Involving Compounds of Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur OpenSysReactors.xls Solution Sheet: Open-System Chemical Reaction Mass and Energy Balances Involving Compounds of Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur PengRobinson.doc Assignment: Solving the Peng-Robinson Equation of State for Real Gas Mixtures PengRobinson.xls Solution Sheet: Solving the Peng-Robinson Equation of State for Real Gas Mixtures ReactionAnalysis.doc Assignment: Mass Balance for Chemical Reaction Involving Compounds of Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur ReactionAnalysis.xls Solution Sheet: Mass Balance for Chemical Reaction Involving Compounds of Carbon, Hydrogen, Nitrogen, Oxygen, and Sulfur ResidentialFurnace.doc Assignment: Choosing a High Efficiency Forced Air Furnace for Residential Heating Service StudentFurnace1.doc Solution Sheet: Sample 1 of Student Solution for Choosing a High Efficiency Forced Air Furnace for Residential Heating Service StudentFurnace2.doc Solution Sheet: Sample 2 of Student Solution for Choosing a High Efficiency Forced Air Furnace for Residential Heating Service
