  The case considered is laminar flow and mass transfer
  of an incompressible, constant-property fluid in the
  developed region of a of a circular tube. The mass transfer
  problem can be solved either with a constant wall mass flux
  ( QFCON=T ) or a constant wall mass concentration ( QFCON=F ).
  The Schmidt number is set to 1.0, but it should be noted that
  the Sherwood number is a function only of the concentration
  boundary condition, as follows: Sh = 3.656 for a constant wall
  mass concentration and Sh = 4.364 for a constant wall mass flux
  QIN. For the latter case, an analytical solution exists for the
  radial concentration profile which is programmed below in PIL.
  The analytical velocity profile, which is parabolic, is also
  coded below.
