DETERMINATION OF VOLUME FLOW RATE AND ENERGY EFFICIENCY OF TWIN OIL PIPELINE SYSTEMS

The expediency of the method of hydraulic calculation of twin oil pipelines with using the conception of equivalent diameter for all zones of friction of turbulent regime was investigated. On the basis of the universal modified Kolbrook formula for the friction factor in turbulent flow regime, a method for determining the volume flow rate and energy efficiency of twin oil pipeline without the use of an equivalent diameter was developed. This method was tested in determining the parameters of the existing oil transportation system.
