metadata.value: Basic approaches to deﬁning the coeﬃcient of hydraulic resistance and the total heat transfer coeﬃcient between the gas and the ambient in the model of an unsteady nonisothermal gas ﬂow through an oﬀshore gas-pipelines are considered. Model sensitivity to variations of these coeﬃcients is illustrated by the charts, demonstrating inﬂuence of these coeﬃcients on the basic ﬂow characteristics. The coeﬃcient of hydraulic resistance and the heat transfer coeﬃcient calculations for one from test variant of gas transmission are given. The calculation method of these parameters from the experimental date, enabling to provide the validity of model of the unsteady nonisothermal gas ﬂow through a sea gas pipeline when calculating certain pipeline is suggested.
