Relationship to Student Outcomes
No student outcomes specified.
Course Learning Outcomes. Students will:

1. Define the discipline of chemical engineering, including contemporary issues.

2. Describe the professional opportunities available to chemical engineers.

3. Draw and fully label a flowchart for a written process description, choose a convenient basis, perform degrees-of-freedom analysis, and calculate the required process variables for the overall system.

4. Use component mole balances, the extent of reaction methodology, and atomic species balances to solve material balance problems with reactions.

5. Calculate the feed rate of air for a combustion reaction, given the fuel composition and percent excess air.

6. Apply the ideal gas law to determine any of the four quantities: a) temperature, b) pressure, c) mole number, or d) volume, when the other three are given.

7. Estimate the vapor pressure of pure, non-aqueous substances at a specified temperature, or the boiling point at a specified pressure, using: a) the Antoine equation, b) the Cox chart, or c) the Clausius-Clapeyron equation.

8. Estimate the vapor pressure of pure water at a specified temperature, or the boiling point at a specified pressure, using the steam tables.
