ABSTRACT:
The present invention deals with a method which allows to determine the wall friction profile along pipes transporting liquids, particularly petroleum industry liquids, by measuring the pressure transients induced by fast changes in the flow rate. This method is applicable to pipes in which the discharge pressure is greater then the bubble point of the transported liquid and, in any case, when free gas is absent in the pipe.
