An analytical study of the friction law for rectilinear flow a Phan-Thien-Tanner fluid is presented. The flow is assumed steady and the pipe circular. The equations of motion are solved and the velocity, rate of flow, and friction factor are determined. Friction effects are related to the Reynolds number and to other flow parameters, such as the Deborah number.
