Prerequisites - Accomplishment
Students entering ChE 201 should be approaching mastery of the
following skills, which will be reinforced in ChE 201:
- Explain the purpose of flash tanks, reactors, pumps, evaporators, distillation columns,
liquid-liquid extraction columns, and crystallizers.

correctly complete a calculation.
- Comment m-files and format output appropriately (labels, units, etc.).
- Use "for" and "if-then" structures and counters.
- Perform calculations with scalars, vectors, and arrays.
- Properly distinguish between element-by-element and array operations.
- Use fsolve or fzero to complete a "trial-and-error"-type solution of a single equation.
- Make plots with labeled axes.
