Problems of Heavy Oil Transportation in Pipelines And Reduction of High Viscosity
Iraqi Journal of Chemical and Petroleum Engineering, 2015 Drag has long been identified as the main reason for the loss of energy in fluid transmission like pipelines and other similar transportation channels. The main contributor to this drag is the viscosity as well as friction against the pipe walls, which ...
