15 CHEMICAL ENGINEERING
QUESTIONS AND VERIFIED
ANSWERS|100% CORRECT|GRADE A+
Chemical Engineering - ANSWER The branch of engineering that deals mostly with the large-scale
production of chemical products.
American Institute of Chemical Engineers (AIChE) - ANSWER Largest professional organization specific to
environmental engineering
Chemistry - ANSWER Scientific study of materials, their properties, their interactions, and the changes
that they undergo
Thermodynamics - ANSWER Study of work, energy, and efficiency in large-scale systems
First Law of Thermodynamics - ANSWER Application of the law of conservation of energy, which states
that energy cannot be created or destroyed.
Second Law of Thermodynamics - ANSWER Often called the entropy law, this law is concerned with the
idea that concentrated sources of energy will naturally disperse
Entropy - ANSWER Tendency of all energy and matter to seek a state of uniformity
Zeroth Law - ANSWER Observation dealing with thermodynamic equilibrium
Mass Balance - ANSWER Property founded in the law of the conservation of matter, which states that
matter cannot be created or destroyed and, therefore, must be constant in a closed loop
Differential Balances - ANSWER Type of balance that is taken at the same point over time.
Integral Balances - ANSWER Type of balance that is taken at two different points to show what is
happening between one point and another. It is typically taken at the beginning and end of a process.
, Fluid Dyanmics - ANSWER Study of fluid flow
Fluid Flow - ANSWER Liquids or gases in motion
Viscosity - ANSWER Thickness of a liquid, or its resistance to being deformed
Surface Tension - ANSWER Characteristics almost like a film on the surface, caused by the molecules of a
liquid tending to be more attracted to each other than they are to their surrounding materials.
Turbulent Flow - ANSWER Chaotic or abnormal flow consisting of swirls, or eddies
Laminar Flow - ANSWER Type of flow that has no disruption between the layers of the moving fluid, with
no eddies or changes
Deformulation - ANSWER Process that involves the identification and separation of chemical
components within a substance.
Differential Pressure Flowmeters - ANSWER Type of flowmeter that constricts the flow by placing some
sort of obstruction inside of a pipe or by narrowing the pipe at a point.
Velocity Flowmeters - ANSWER Type of flowmeter that measures the speed of passing fluid and the
depth of the field.
Mechanical Flowmeters - ANSWER Type of flowmeter that uses a variety of mechanical devices inside of
a pipe to measure flow.
Mass Flowmeters - ANSWER Type of flowmeter that measures the mass rather than the volume.
Open-Channel Flowmeters - ANSWER Type of flowmeter that measures the flow in a channel rather than
in a pipe.
