I like to hang 0.9% NS to gravity when possible because I always thought that the fluids would stop infusing if the IV site blows. A co-worker of mine disagrees and said that IV fluids hung to gravity would continue to flow and infiltrate if an IV site blows.
For turbulent flow, the difference is about 10%. For non-Newtonian fluids, the effect is less but still significant. In deviated wells, the drillpipe should be fully eccentric over much of the deviated wellbore, resulting in reduced fluid friction. Define the correction factor for eccentricity. .....(59)
