SIGNIFICANCE OF THE PRESSURE GRADIENT ON FULLY DEVELOPED TURBULENT FLOW IN A PIPE

The assumption of negligible pressure-gradient effects on the momentum transfer for flow conditions such as hydrodynamically fully developed tube flow has generally been justified by dimensional-analysis--order-of-magnitude arguments. Because of the pertinence of this formulation in obtaining an analogical relationship for the mean frequency of surface renewal, a more rigorous analysis of the effect of the pressure gradient is presented for incompressible flow.
