Summary. The impact of oil discharge (pumping) volume on the flow rate in the initial section of the pipeline and the head value at the station inlet, where the discharge (pumping) is done, was studied. The algorithm and software to determine the flow rate at the initial section depending on the discharge (pumping) volume were developed.

Keywords: fluid flow rate, periodical discharge, periodical pumping, main oil pipeline.

Summary. The dependence of flow capacity on the value of the output overpressure of gas control point and the dependence of minimum overpressure at the exit of the gas control point on gas consumption by network were studied.

As a result, the analytical expression that helps to define the minimum excess gas pressure at the outlet of the gas control point, which provides the required gas flow rate and allowable pressure losses in the network, was developed.

Keywords: gas network, gas control point, flow rate, flow capacity, energy efficiency.

Summary: Basing on the results of industrial experiments, carried out on the real pipeline, the patterns of flowrate changes during unsteady processes, caused by a changing the number of working units at oil pumping stations, were established. The method of determining mean oil flowrate against time and length was developed, which allows to specify the flow capacity of the oil pipeline during unsteady processes in operation.

Keywords: unsteady hydrodynamic process, oil flowrate, flow capacity, pumping units start.

Key words: Architecture, art, personality, aesthetic development, a sense of beauty.

Summary: The method of mathematical modeling characteristics of pumping units for oil pipelines rotary frequency was improved. For recalculation were used graphic characteristics of pumps, obtained experimentally for the nominal value of rotational frequency. The method is based on the application of similarity theory of centrifugal machines.

Summary: The duration of transient process of change in volume flow in oil pipeline by startup of pumping unit in oil pumping station (OPS) was determined with the help of processed industrial data after experiments carried out on the working oil pipeline. For each of the three stages of the transient process were built polynomial models in change of volume flow of oil at the time on the OPS where was launched pumping unit of OM series.
