6. Specific goals for the course

a. The student will be able to…

  • Describe careers that some chemical engineers pursue, and to describe to a high school student what a chemical engineer does;  
  • Use modern engineering tools (MathCAD®, and Excel) to solve basic engineering and math problems that are part of material balance calculations (plotting, use of arrays and matrices, simple programming operations, formulas);  
  • Generate two-dimensional plots, perform linear regression and solve systems of linear algebraic equations; 
  • Correctly implement engineering calculations: unit conversions; units of mass and weight, significant figures;
  • Understand the importance of validating results;
  • Convert between mass and mole fractions in a mixture;
  • Explain the difference and convert between absolute and relative pressure and temperature scales;
  • Draw and label a correct diagram (flowchart) given a problem statement;
  • Choose a basis of calculation;
  • Correctly perform a degree of freedom analysis;
  • Analyze and solve elementary material balances on single and multi-unit process, for both nonreactive and reactive processes;
  • Solve material balance calculations with: recycle, purge, fractional conversion of the limiting reactant, percentage excess of a reactant, yield and selectivity, dry-basis composition, theoretical air and percent excess air;
  • Use equations of state for single-phase property calculations;
  • Use “standard” volumes for gases;
  • Calculate vapor pressures;
  • Use Raoult’s and Henry’s law;
  • Sketch a phase diagram; and
  • Calculate bubble points and dew points for ideal solutions.
