The art of being a good chemical engineer is being able to quickly understand relationships between various phenomena. We oftentimes compare process variables (flow rate, temperature, pressure, etc.) to develop a mathematical understanding of a particular situation. Reactant concentration versus time, distillation pressure versus distillate (or bottoms) composition, and inlet flow rate versus outlet stream temperature of a heat exchanger are just a few of these. In gas chromatograph (GC), the GC converts a signal output (usually in mV) into a peak area. Calibration curves are made by testing the peak areas for different concentrations of a mixture and then fitting those areas to a linear expression. Using linear regression, develop the calibration curve for this dataset of various concentrations for monoethanolamine in toluene. DONT USE EXCEL. hand written solution and graph only.
