Basics of mathematics and chemistry.

Students should be aware of the significance of chemical and biological industries to a sustainable development; identify variables and classify different process types; interpret manufacturing diagrams and flowsheets.

This course unit?s purpose is to provide:
(a) an integrated and strategic overview of the chemical/biological process engineering applied to the major industrial sectors and their integration on the modern society;
(b) an introduction to the chemical engineering calculations;
(c) definitions, illustrative measurement techniques and methods of calculating variables that characterize the operation of processes.
After completing this course the students should be able to:
(a) understanding the significance of chemical/biological industries to a sustainable development;
(b) convert units using; identify the number of significant figures; explain the concept of dimensional homogeneity of equations; use linear interpolation; fitting linear and nonlinear data; use scientific calculators and spreadsheets for the representation and analysis of data;
(c) identify variables and classify different types of processes; interpret manufacturing diagrams and their corresponding flow sheets.
