For a first order process G(s)= 4/(s+0.5):
(a) Qualitatively sketch the pattern of the Bode diagram for
this process, and indicate the limiting behaviors( i.e., the slopes
and values as s --> 0 and s --> infinity) of ARn( the
normalized amplitude ratio) and Phi ( the phase shift) in the
plots.
(b) Will a P-only control possibly make the process unstable?
Show your reasoning based on the Bode stability criterion.
(c) What if a delay term e^-5s is included,...
Sketch a PV diagram for a pure substance. Include several
isotherms and phase envelopes. Label the solid, gas/vapor,
liquid/vapor, liquid, solid/liquid, and solid/vapor phases. For the
liquid, vapor/liquid, and gas/vapor regions, indicate an
appropriate equation of state for predicting PVT data in the
phase.
All one question with a few different parts
Use the data to sketch the phase diagram for xenon (Xe) and then
answer the questions that follow.
Normal boiling point: 165 K
Normal melting point: 161 K
Triple point: 152 K, .37 atm
Critical temperature: 290 K
Critical pressure: 57 atm
A. What phase is xenon at atmospheric conditions?
B. Is liquid xenon more or less dense than solid xenon? Use the
diagram to justify your answer.
C. What is the...
Using the Standard Trade Model, show by means of a diagram how a
country can gain from trade, explaining how a change in the
relative price of one good leads to a gain.
Be as specific as possible with the diagram and label and
explain everything clearly
How do you Plot a Bode Phase Plot
1. how do you graph a pole
2. How do you graph a zero
3.How do you graph a pole at origin(what does that mean)
4. How do you graph a zero at origin.
Please illustrate 1-4 on a graph. indicating which is which

Consider the diagram to the right. The “initial” sketch illustrates, both at the macroscopic and molecular levels, an initial condition: 1 mol of a gas at 273 K and 1.00 bar. With as much detail as possible, illustrate the final condition after each of the following changes.(a) The pressure is changed to 250 mmHg while standard temperature is maintained.(b) The temperature is changed to 140 K while standard pressure is maintained.(c) The pressure is changed to 0.5 bar while the...

Compare and contrast, using a diagram or otherwise, how the
magnetic domains align in an applied magnetic field for
diamagnetic, paramagnetic, and ferromagnetic materials. Give an
indication of the magnetic susceptibilities in each case. Estimate
the saturation magnetisation (units A/m) for Nickel assuming 0.6
Bohr Magnetons per atom and a density of 8.91 gcm-3.
