**Q1**
Predict how the boundary layer grows with *x*
as a function of Pe.

**Q2**
Predict/confirm the extent of the region near
the "leading edge" over which axial conduction effects will be
felt.

**Q3**
Predict the distance downstream at which the
temperature profile will become (*a*) fully developed, and then (*b*)
uniform.

**Q4**
Show the output variation with Pe and *L*
in particular for low and high Pe.
