Chemical Reaction Engineering
This type of reactor has reactants loaded in the beginning. As the reaction proceeds, more reactant is added. Once the reaction is complete, the reactor is emptied.
What is a semi-batch or fed-batch reactor?
When a vapor is cooled slowly at constant pressure, this is the temperature at which the first liquid droplet forms.
What is the dew-point temperature?
This third law of thermodynamics specifies this property as zero for perfect crystalline substances at absolute zero temperature.
What is entropy?
Assumption made when the Biot number is less than 0.1
What is the lumped solution assumption? (uniform temperature throughout body during transient heat transfer)
This professor walks a 5K every day.
Who is Dr. Crunkleton?
Ea in the Arrhenius equation
A exp(− Ea/RT)
What is the activation energy?
This type of stream is used to send unused raw material emerging from a process unit back to the unit.
What is a recycle stream?
Cp – Cv equals this for an ideal gas.
What is R (the gas constant)?
This law describes the power radiated from a black body in terms of its temperature
What is the Stefan-Boltzmann Law? (Stefan’s Law)
This professor starts their day with the New York Times Games app (at least before it was paywalled)
Who is Dr. Weston?
This is defined as the ratio of desired to undesired product.
What is the Selectivity?
This is the primary reason that a purge stream is used in a reactive process
What is avoiding the accumulation of an inert substance?
An enthalpy-entropy diagram is commonly called this in recognition of its creator.
What is a Mollier diagram?
The equation Q = hA(T∞ - Tw) is named after this scientist.
Who is Sir Isaac Newton?
This professor keeps soup in the faculty fridge
This is the probability distribution function that describes the ages a fluid element spends in the exit stream
What is the residence time distribution?
The specific gravity of a liquid or solid is based on the density of water at this temperature.
What is 4ºC (39ºF)?
Equation of state given by P = [RT/V - b] - [a/(V2 + 2bV - b2)]
What is the Peng-Robinson Equation of State?
This dimensionless number is the product of the Grashof number and Prandtl number.
What is the Rayleigh number?
This professor is a gym rat.
Who is Dr. Daraboina?
Methylcyclopentadienyl manganese tricarbonyl (MCMT) produced during the 2007 T2 Laboratories explosion in Jacksonville, Florida is used as an additive to this widely used material.
What is gasoline?
This “law” states that the volume of a gas mixture is the sum of the pure component volumes.
What is Amagat’s Law?
This, according to the Gibbs’ Phase Rule, is the degrees of freedom for pure liquid water (1 phase).
What is 2? (F = 2 – π + N = 2 – 1 + 1 = 2)
This parameter is defined as the following.
α = k / ρ . C p
What is thermal diffusivity?
This professor switched from pre-med to chemical engineering after organic chemistry
Who is Dr. Crunkleton?
