CHEMICAL ENGINEERING.
Built around real course units and objectives!
Largest professional organization of Chemical Engineers - Answer: American Institute of
Chemical Engineers
Alche
Chemistry - Answer: Scientific study of materials, their composition and structure, their
Properties, their interactions, and changes they undergo.
Thermodynamics - Answer: Study of work, energy, and efficiency in large-scale systems
Zeroth Law - Answer: Thermal Equilibrium
First Law - Answer: Law of conservation of energy
Second Law - Answer: Energy will naturally disperse; Entropy law
Entropy - Answer: The tendency of all energy and matter to seek a state of uniformity.
Third Law - Answer: The colder a substance gets, the less its atoms move
Fluid Dynamics - Answer: Study of fluid flow
Viscocity - Answer: Liquid thickness, resistance to being deformed.
Surface tension - Answer: Characteristic created by liquid molecules being attracted to
each other.
Turbulent Flow - Answer: Velocity fluctuations;highly disordered.

, Swirls of water - Answer: Eddies
As turbulent flow increases... - Answer: Energy increases needed to move it
Laminar Flow - Answer: No disruption between layers of fluid. Smooth, viscous forces
dominate.
Reynold's number equation - Answer: Density(velocity)(diameter of pipe)/dynamic
viscosity.
Reynold's number ratios of inertia to viscosity - Answer: Under 2300 = Laminar
Over 10000 = Turbulent
Mass Balance - Answer: States that matter cannot be created or
Destroyed and must be constant in closed loop
Differential Mass Balance - Answer: measurement taken at the same
Point over time.
Applied to a continuous process.
Should always be the same.
Each term in a differential balance equation represents a
Process stream and the mass flow rate of the chemical(s) in that
Stream.
Integral Mass balances - Answer: taken at two different points to
Show what is happening between one point and another
Typically taken at beginning and end of process
