#### 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.
