Processes and Problem solving in engineering.

Week 2 Part I Chemical Engineering Calculation.

Units and Conversion Systems of units, conversion. Significant figures.

Forces and weight. Dimensional homogeneity and dimensionless

quantities.

Week 3 Sample mean and sample variance. Process data representation and

analysis (2 pts interpolation, introduction to least square method). Curve

fitting non linear relationship.

Week 4 Part II - Process and process variables.

mass, volume, density, specific gravity. Flow rates. Chemical

composition (mole, lb-mole, molecular weigth, mass and mole fractions,

average molecular weight of mixtures, concentration). Parts per million

and parts per billion.

Week 5 Pressure: Fluid pressure and hydrostatic head. Absolute pressure and

pressure gauge. Fluid pressure measurement (bourdon gauge,

manometer).

Week 6 Part III - Material balance

Flowchart representation of a unit/process. General material balance

equation. Material balance for a batch process. Material balance for a

steady-state continuous process. Material balance for a semi-batch

process.

Week 7 Material balance on multiple unit operation. Degree of freedom analysis.

Series of problems done in class for material balance without reactions.

Material balance with recycle stream.

Week 8 Material balance with reactions: terminology (extent of reaction, single

vs. multiple reactions. Series of problems done in class for material

balance with reactions.

Week 9 Material balance with reaction, product separation and recycle. Material

balance on reactive system with recycle and purge. Series of problems

done in class on material balance involving reaction, recycle and purge.
