Question

An infinite sequence of CSTRs is equivalent to what?

Answer #1

In an ideal cstr there is perfect mixing. Also as soon as the reactant enters the reactor it mixes and gets converted to product but as soon as it enters, it gets converted and the concentration suddenly drop. as keep on adding CSTR in series, we will have perfect 100 % in each reactor

This can be looked as a PFR where in we have no axial mixing but 100% radial mixing. Each radial section of a PFR can be looked as a CSTR as each CSTR will have full mixing taking place.

Hence infinite sequence of CSTR will be nothing but a PFR

Does a sequence which converges to 3 in such a way that the
infinite series also converges to some limit exist?

Theorem 16.11 Let A be a set. The set A is infinite if and only
if there is a proper subset B of A
for which there exists a 1–1 correspondence f : A -> B.
Complete the proof of Theorem 16.11 as follows: Begin by
assuming that A is infinite.
Let a1, a2,... be an infinite sequence of distinct elements of A.
(How do we know such a sequence
exists?) Prove that there is a 1–1 correspondence between the...

Read and convert a sequence of digits to its equivalent integer.
Any leading white space should be skipped. The conversion should
include digit characters until a non-digit character is
encountered. Modify the program so it can read and convert a
sequence of digit characters preceded by a sign, + or -.

Suppose A is an infinite set and B is countable and disjoint
from A. Prove that the union A U B is equivalent to A by defining a
bijection f: A ----> A U B.
Thus, adding a countably infinite set to an infinite set does
not increase its size.

Find an example of a sequence, {xn}, that does
not converge, but has a convergent subsequence.
Explain why {xn} (the divergent sequence) must have an
infinite number of convergent subsequences.

The gaming commission is introducing a new lottery game called
Infinite Progresso. The winner of the Infinite Progresso jackpot
will receive $1,100 at the end of January, $2,500 at the end of
February, $3,900 at the end of March, and so on up to $16,500 at
the end of December. At the beginning of the next year, the
sequence repeats starting at $1,100 in January and ending at
$16,500 in December. This annual sequence of payments repeats
indefinitely. If the...
