Lesson 1

Question 1

the profession in which knowledge of mathematics, chemistry, and other natural sciences gained by study, experience, and practice is applied with judgment to develop economic ways of using materials and energy for the benefit of mankind.

Answer 1

Chemical Engineering, American Institute of Chemical Engineers (2016)

Question 2

the application of the principles of the physical sciences together with the principles of economics and human relations to fields that pertain directly to processes and process equipment in which matter is treated to effect a change in state, energy content or composition

Answer 2

Chemical Engineering, American Institute of Chemical Engineers (1956)

Question 3

Factors in Chemical Processes

Answer 3

1. Unit processes: chemical change
2. Unit operations: physical change
3. Physical chemistry: equilibriums and reaction rates
4. Economics: costs, statistics, and consumption
5. Energy and power: chemical as well as electrical and mechanical

Question 4

A Chemical Engineer is concerned primarily with

Answer 4

the design, construction, and operation of equipment and plants in which these unit operations and unit processes are applied

Question 5

unit operations include

Answer 5

the physical changes in energy or position, such as heat flow, liquid flow, or separation

Question 6

unit processes consider

Answer 6

the change in chemical energy and the resultant effects

Question 7

develop through flow sheets, which are definitely constructed from a coordinated sequence of unit processes and operations that fabricate the raw materials into the finished product and by-products

Answer 7

Chemical Process
