The hydromagnetic mixed convection flow through a porous 
medium in a pipe of varying radius in a uniform axial magnetic field 
is analyzed. The pipe wall is maintained at a prescribed nonuniform 
temperature. The governing equations are solved analytically to obtain 
the velocity, temperature, and induced magnetic field. Their behaviors 
are evaluated for different variations in the governing parameters.
