A process consists of five perfectly stirred tanks in series.The volume in each tank is 30 L, and the volumetric flowrate through the system is 5 L/min. At some particulartime, the inlet concentration of a nonreacting species ischanged from 0.60 to 0.45 (mass fraction) and held there.(a)Write an expression forc5(the concentration leaving thefifth tank) as a function of time.(b)Simulate and plot c₁,c₂,...,c₅. Compare c₅ at t=30 min with the corresponding value for the expression in part (a).

Basic Chemical Calculations (Process and Variables)

A basic chemical calculation involves the application of the law of chemical proportions to various reactions and material and energy balance calculations on various chemical processes. Basic chemical calculation helps students analyze various chemical processes and develop problem-solving skills. The chemical manufacturing processes are divided into unit operations involving physical changes of material and unit processes involving the chemical transformation of materials. For instance, fluid flow, heat transfer, and mass transfer are unit operations, and oxidation, reduction, and pyrolysis are unit processes.
