This module helps students in the introductory chemical engineering course understand and practice the application of material balances to biological systems of different dimensions using an algorithm for the solution of material balance problems. In-depth interactions focus on mass balance problems involving cell metabolism, an artificial kidney, and a cheese factory.

This multimedia tour is used as part of an open-ended project for a material balance course, in which students create a flowsheet for the phosphate coating system at Ford Motor Companyís Wixom plant, then suggest modifications for waste minimization.

This module introduces students to the applications of material balances in wastewater treatment processes. After reviewing the basics of wastewater treatment, students can take a tour of the Ann Arbor Wastewater Treatment Plant. A quiz includes material balance questions corresponding to each section of the plant.

This interactive module helps students understand the use of Pxy and Txy diagrams in describing binary liquid-vapor systems. The module also includes a review, introduction to industrial uses, and three quizzes to evaluate their understanding of the diagrams and their use. 

Using this module, students learn how to read and use psychrometric charts, and are exposed to industrial applications in which they are used. Three quizzes help students evaluate whether they understand the components of the chart, how to locate a point on the chart, and how to follow a process using the chart.

This module helps students review how to read and use enthalpy concentration diagrams, and explore applications in which enthalpy concentration diagrams are used. A quiz helps students determine if they understand the components of the diagram, how to locate a point on the diagram, and how to follow a process using the diagram to solve material and energy balance problems.
