WebMay 1, 1990 · Summary. In this study, the effects of pipe roughness on friction pressures of uncrosslinked and crosslinked fracturing gels are reported from flow data gathered in smooth and rough pipes. Pipe-roughness effects are found to be very significant in the estimation of friction pressures of fracturing fluids. These effects are more pronounced … WebOn the other hand, in fully developed turbulent flow, for Reynolds numbers over 2,000–2,300 and for a rough pipe, friction factor is a sole function of the pipe's relative roughness. There exists a transition region between smooth wall flow and fully developed turbulent flow where the value of friction factor is determined by both N Re and k values.
