Operation of gas pipelines

Task number 1
Determine the throughput of the MG section with a length l = (130 2n ٭) kilometers and an inner diameter D = (1250-10n) millimeters. The pressure and temperature of the gas at the beginning of the section P1 = (6.61 - 0.05n) MPa and T1 = (282.5 - 0.5n) K. The pressure at the end of the section P2 = 5.0 MPa. Soil temperature T0 = (276.75 0.25n). Gas with a relative density Δ = (0.59 0.002n) is transported. Assess the effect of accuracy in determining the temperature and gas pressure on the accuracy of determining the throughput of a site.
Laboratory work No. 1
Investigation of the gas flow in the MG section.
Objective. Establish patterns of gas flow through a gas pipeline.
Tasks of work:
1) familiarization with application programs and with the characteristics of the experimental site;
2) planning and conducting an experiment to study the distribution of pressure along the length of the plot. The required accuracy in determining the pressure is set by the teacher;
3) processing the results of the experiment;
4) presentation of the results of the experiment and calculations in the form of graphs of pressure, pressure squared, temperature, density and gas flow velocity along the length of the section;
5) draw conclusions about the nature of the distribution of the studied parameters along the length of the plot and about the factors and physical quantities that determine it.
