The study of peristaltic flow of an incompressible non-Newtonian Prandtl fluid model has been explained in
three dimensional rectangular channels. All the corresponding equations have been derived in three dimensional coordinate system. The governing equations have been solved analytically to achieve the expressions for velocity and pressure gradient while pressure rise data has been acquired numerically. The physical aspects of appertaining quantities have been enlightened through graphical assistance in both two and three dimensions. The stream functions have also been delineated for all the inclusive parameters.
