2026!!!
1. about chemical -Deals mostly with large-scale production of chemical products
engineering -Responsible for the invention of new processes
-Designs and operates facilities that create chemical compounds on a large scale.
-Largest professional organization is American Institute of Chemical Engineers
(AIChE)
2. what are the chemistry, thermodynamics, and fluid dynamics
chemical engi-
neering princi-
ples?
3. what is chem- Scientific study of materials, their composition and structure, their properties, their
istry? interactions, and changes they undergo
4. what is thermo- Study of work, energy, and eflciency in large-scale systems
dynamics?
5. what is the zeroth Associative law of equilibrium
law of thermody- -If two objects are each the same temperature as the third, then they are in
namics? equilibrium with each other.
-Ex; Object A is temperature C. Object B is also temperature C. Object A is in
equilibrium with object B
6. what is the first Energy cannot be created or destroyed (law of conservation of energy)
law of thermody-
namics?
7. what is the sec- Energy will naturally disperse; Entropy Law
ond law of ther- -Entropy: the tendency of all energy and matter to seek a state of uniformity.
modynamics? -Example; Hot beverage will eventually reach room temperature
-Process is not reversible - cup will not heat up by itself
-100% eflciency is impossible

8. what is the third The colder a substance gets, the less its atoms move. absolute zero cannot be
law of thermody- reached.
namics?
9. what is fluid dy- study of fluid flow
namics?
10. what is viscosity? liquid's thickness, resistance to being deformed.
11. what is surface characteristic created by liquid molecules being attracted to each other
tension?
12. what is turbulent -Velocity fluctuations; highly disordered
flow? contains swirls of water called eddies
-Ex; dragging your hand through the water creates swirls.
-Fluid particles flow in many directions with no observable paths or layers
-As turbulent flow increases, so does energy needed to move it
13. what is laminar -has no disruption between layers of fluid
flow? -Smooth streamlines, highly ordered
-Little or no mixing; particles flow in a straight path
-Viscous forces dominate
14. what is lami- Characterized by Reynolds number: density(velocity)(diameter of pipe) / dynamic
nar flow charac- viscosity
terized by? -Ratio of inertia to viscosity
-Under 2,300 => Laminar
-Over 10,000 => Turbulent
15. what are applica- Aerodynamic design of planes / cars
tions of laminar
flow?
