Derive an one-dimensional neutron transport equation from the
equation above, a steady-state neutron transport equation applying
to the one-dimensional slab geometry.
In
applying bernoulli’s equation, derive an equation for the pressure
at the inlet of the nozzle below to produce a flowrate of
Q=0.70ft^3/s. If the nozzle doscharges to atmosphere at point 2.
Take diameters D1=3’’ and D2=1’’
Derive the heat equation for a homogeneous one-dimensional rod
with a non-constant crosssection of area A(x) and perimeter P(x).
Suppose that the lateral surface is not insulated and the amount of
heat energy leaving the rod via the lateral surface per unit area
per unit time is proportional to the difference of the temperature
in the rod and the temperature w(x, t) of the air surrounding the
rod (use the coefficient of proportionality α). Furthermore,
suppose that there are no...

Derive and discuss the steady state flux of one species,
H2O, where no chemical reaction occurs. Investigate the
diffusion of H2O and show the complete derivation using
Fick's First Law and discuss the mass transfer in such a system
containing only one species and no chemical reaction occurs.
Assuming that a neutron confined to a nucleus can be modeled as
a one-dimensional infinite square well with width 10*10^-15m,
answer the following:
a. What is the minimum energy of the neutron (in MeV)?
b. What would the minimum energy of an electron in the nucleus
be? Based on this result, could an electron be contained in a
nucleus? Explain.
(e) In the steady state and above threshold, why will the gain
and carrier density inside a semiconductor laser be clamped
(limited)to the threshold condition? How about photon density
inside the cavity? If the driving current is time varying form, are
gain and carrier density still kept in constant values? How about
in AC driving conditions?
