FULLY CORRECT
⫸ Material Balance Answer: A principle stating that the input to a
system minus the output plus any generation equals the accumulation
within the system.
⫸ Steady State Answer: A condition in which the properties of a system
remain constant over time, implying that accumulation is zero (A=0).
⫸ Transient State Answer: A condition in which the properties of a
system change over time until it reaches a steady state.
⫸ Types of Chemical Processes Answer: The main categories of
chemical processes include batch processes, where materials are
processed in discrete quantities, and continuous processes, where
materials are processed without interruption.
⫸ Problem Solving Steps Answer: A systematic approach to solving
engineering problems that includes: 1) Draw a diagram, 2) Determine
the knowns and unknowns, 3) Write the relevant equations, 4) Solve the
equations, 5) Check your solution.
, ⫸ Continuity Equation Answer: An equation that represents the
conservation of mass in fluid flow, expressed as A₁V₁ = A₂V₂, where A
is the cross-sectional area and V is the velocity.
⫸ Heat Transfer Modes Answer: The three primary modes of heat
transfer are conduction (heat transfer through direct contact), convection
(heat transfer through fluid motion), and radiation (heat transfer through
electromagnetic waves).
⫸ open system Answer: both matter and energy can be exchanged (add
slides def)
⫸ In a batch process, what is true? Answer: inputs and outputs occur
only at the beginning and the end
⫸ generation is NONZERO only when... Answer: a chemical reaction
occurs inside the system
⫸ A student models an absorber tower and assumes steady-state
operation. Which of the following conditions must hold true? Answer:
Input gas flow = Output gas flow for each component
⫸ closed system Answer: only energy can be exchanged, not matter
