Hi,
I would like the numerical solution for this task so I can be able to model it in a kinetic modeling programme like Berkely Madonna (BM). This was the reason why I started my membership with Chegg Study but unfortunately, the solution to this problem was not available. I'm looking forward to hearing from you.
you will find the task in de link below.
With kind regards,
Ahmed

Base your answers to the following questions on the analogies
drawn for the collision mechanisms between suspended particles in
coagulation/flocculation and between a suspended particle and a
static collector grain in filtration.
a) List four types of physical transport (collision) mechanisms
that are important to filtration and their analog among
flocculation transport mechanisms (if any).
b) Which mechanism(s) would be expected to govern the collection
efficiency of 0.4 micrometer particles passing into a filter?
c) If the media grain size were increased, which mechanism(s) would
decrease in effectiveness of collection?
d) If the density of the influent particles increased which
mechanism(s) would increase in collection effectiveness?
e) If the approach (superficial) velocity increases, which
mechanism(s) would decrease in effectiveness of collection?

a.) Develop equations for X and S as a function of dilution rate for a continuous cell culture system. Assuming that the kinetics are governed by an uncompetetive inhibition model.
b.) Plot X, S and "yield of cell mass (g cells/l) per time" versus dilution rate and recommend a dilution rate to operate the reactor at if:
So = 20 g/l
Ks = 1 g/l
I = 0.08 g/l
Y x/s = 0.2 g cells/g substrate
Xo= 0
KI = .02 g/l

Rayleigh distillation
An aqueous solution of acetic acid is to be enriched by simple (differential) distillation.
The flask is initially charged with 0.025 kmol of solution of composition 0.600 mol
fraction water.
a)
Distillation is continued until the composition of the liquid in the flask has fallen
to 0.300 mol fraction water. Assuming that the vapour is completely condensed
and collected in a cooled receiver, calculate the quantity and composition of the
distillate.
b)
Repeat the calculation for the case in which distillation is stopped when the
composition of the liquid in the still has reached 0.500 mol fraction water.
c)
Explain why separation is so poor, particularly in case (a).

4.14 (a) Calculate the diffusion coefficient for oxygen ions in a pure ZrO2 electrolyte at T = 1000∘C given ΔGact = 100 kJ∕mol, ?0 = 1013 Hz. ZrO2 has a cubic unit cell with a lattice constant a = 5 Å and contains four Zr atoms and eight O atoms. Assume that the oxygen–oxygen “jump”distance Δx = 1 2 a. (b) Calculate the intrinsic carrier concentration in the electrolyte givenΔh? = 1 eV. (Assume vacancies are the dominant carrier.) (c) From your answers in (a) and (b), calculate the intrinsic conductivity of this electrolyte at 1000∘C.
