Abstract:

The article presents the results of calculations of key technological parameters for the storage and pumping of motor gasoline at gas stations. Three typical engineering tasks are considered: determining product losses from "breathing" of a tank RVS-5000, calculating the gravity flow time for unloading gasoline from a tank truck AC-10-260 into a receiving reservoir, and estimating the leakage volume through a corrosion pinhole in a tank wall. The solutions are based on methods of hydraulics, thermal physics, and mass transfer, including calculations of flow coefficients, Reynolds numbers, flow regimes, and balance equations for the gas space of the reservoir. The obtained results (breathing losses ≈ 0.47 of saturated vapor concentration, unloading time ≈ 1026 s, leakage volume ≈ 0.019 m³) allow assessing the efficiency and safety of gas station equipment operation. The presented calculations can be used in the design and reconstruction of fueling complexes to reduce operational losses and optimize technological modes.
