Abstract
This work aims at the study of loss of charge in single phase and biphasic flows, from a sample of data obtained with empirical tests in an experimental apparatus. Liquid and air flow values were selected for the tests, obtaining main results of Reynolds number, void fraction and reduction of trawl in the pipeline. The results obtained could be explained with a friction analysis of the flow with the walls of the pipe. The roughness of the pipe was a determining factor for the loss of load in the single phase flow. The presence of the gas phase was determinant for the reduction of the loss of load along the pipe, due to the reduction of the friction of the flow with the walls.
