Abstract: The peristaltic flow of a Walter's B fluid in an endoscope was studied.The problem was model in cylindrical coordinates system.The main theme of the present analysis was to study the endoscopic effects on the peristaltic flow of Walter's B fluid,because to the best of authors'knowledge no investigation had been made up to yet in peristaltic literature to study the Walter's B fluid in an endoscope.The analytical solutions were carried out using regular perturbation method by taking delta as erturbation parameter.The approximate analytical solutions for pressure rise and friction forces were evaluated using numerical integration.The effects of emerging parameters of Walter's B fluid were presented graphically.-
