Consider the fixed laminar glide of a mucilaginous clear through a covet round cylindrical tube. The governing equation is

where w is the axial (i.e., z) factor of rapidity, µ is the viscosity, and fo is the gradient of urgency (which includes the completely property of static urgency and gravitational power). The boundary conditions are

Using the harmony and (a) two straight atoms, (b) one quadratic atom, mention the rapidity scope and assimilate delay the exact solution at the nodes:
