A container contains 600 kg solution which includes 6% sugar. It is homogeneously stirred. Another solution which includes 15% sugar is entering the container at 1000 kg/h constant flow rate. At the same time, it is also started a constant withdrawal rate at 700 kg/h. Derive an equation that relates the concentration of outlet withdrawal as a function of time. Calculate the concentration after 1.5 hours as well.

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.
