Mass and Energy Balances is a fundamental engineering course. The aim of the course is to teach students the techniques for formulating and analyzing mass and energy balances under various operating units and conditions. Through a variety of problems, students will develop the ability to understand and formulate problems, and apply these skills to real processes. In this way, students are expected to reach a level where they can approach new process designs with an engineering perspective, apply mass and energy balances, and evaluate the results.

After introducing fundamental concepts such as measurement and units, unit systems, pressure, temperature, concentration, and composition, the course covers problem-solving techniques; mass balances in open-system physical processes; mass balances in open systems involving chemical reactions; gas-vapor relationships; the phase diagram of water; equilibrium; vapor pressure; partial pressure; saturation; partial saturation and humidity concepts; formulation of the general energy balance; enthalpy changes without phase transitions; enthalpy changes during phase transitions; and formulation of the general energy balance in systems involving chemical reactions.
