Class Objectives
/Class Outline
Students can study how to calculate material and energy balance and stoichiometric relation to understand chemical process and quantitative approach. Students can acquire basic method to understand whole picture of chemical process required as a chemical engineer by this lecture. This method is one of basic common methods to apply chemical industry, various manufacturing industries, biotechnology industries and energy industries.

The evaluation items are as follows.
1) Students can understand calculation of the chemical process.
2) Students can understand handling of the mass and system of unit.
3) Students can understand the relation of PVT of ideal and real gases.
4) Students can understand calculation of material balance in chemical process.
5) Students can understand the change of physical state and the calculation of enthalpy balance.
