Question

Consider the system show

get the k values for root locus lead compensator

g(s)=4/(s+1)(s+4)

Answer #1

Sketch the root locus of the given unity feedback system G(s) =
(s+1)/(s^(2) (s-1)) show Ga and Oa on the plot

G(s) = K / s(s+4) (s+5)
H(s) =1, Calculate the value for K and sketch the root locus as K
moves from zero to infinity. What are the seven steps to plotting
the root locus of any feedback system.

Hey, need to solve root locus, find k, kp, and e(infinity), hand
sketch root locus (no need fance Matlab unless you want too).
G(S)H(s)= (s+4)(s+3) / (s+1)(s+2)

Ex. 445. G(s)=k(s+7)/(s(s+12)(s+17)) is the FTF of a unity-
feedback closed-loop system. Sketch the root locus with respect to k. Determine
the number of asymptotes, N. Determine the angle, A, in degrees between the
asymptotes. Determine the angles, [B,C], in degrees of the asymptotes (let B<C).
Asymptote angles: -180<angle<0 and 0<angle<=180
Determine the asymptote centroid, s=D. Answers: N,A,B,C, and D. ans:5

Consider the following reaction at 195 K:
2Cu2O (s) ----> 4 Cu (s) + O2 (g)
In one of your laboratory experiments, you determine the
equilibrium constant for this process, at 195 K, is 5.060E-84. You
are given a table of data that indicates the standard heat of
formation (deltaHform) of Cu2O is -170 kJ/mol. Based on this
information, what is the stnadard entropy change (deltaSrxn) for
this reaction at 195 K? (answer in J/K). Show all work please!

Consider the reaction: C(s) + CO2(g) = 2CO(g)
Kp=168 at 1273 K
A). A system containing these ingredients is at equilibrium, and
the partial pressure of CO2(g) is found to be 0.10 atm.
What is the pressure of CO(g) under these conditions?
B). What is the value of Kc for the reaction at 1273
K?

Given the values of K shown below, determine the value of K for
the reaction,
N2(g) + 2 O2(g) <=> 2 NO2(g).
N2(g) + O2(g) <=> 2 NO(g) K = 92
NO2(g) <=> NO + 1/2 O2(g) K = 36
the answer is 0.0710 please show work to how to get that
answer

Consider the following equilibrium system: 3 Fe (s) + 4 H2O(g) ⇄
Fe3O4 (s) + 4 H2 (g) State what affect each of the following will
have on this system in terms of shifting.
21. The volume of the vessel is decreased
22. The pressure is decreased
23. More Fe is added to the system
24. Some Fe3O4 is removed from the system
25. A catalyst is added to the system

Using the binomial expansion, find the fourth root of
247. Show your work explicitly. Hint: Consider the binomial
expansion of (x4 ± a)^1/4 where you factor out the x^4 and then get
the root by expanding x(1 ± a/x^4)^1/4.

1. For the system defined by f(x) = kx, consider the different
possible values of k. Sometimes the phase line diagram (hopping
diagram) looks similar for different k values; sometimes the phase
line diagrams look very different. Determine the different types of
phase line diagrams that can occur and indicate which k values are
associated with which phase line diagrams.
