Product description

Option 2
Oil in the amount of 350 m3 / h with parameters ρ20, [kg / m3] is pumped through an oil pipeline with a length of L, km, diameter 377 × 10 mm; ν10 and ν60, [m2 / hour]; heated to tach. [0С]. The depth of the underground non-insulated oil pipeline N, [m] and the coefficient of thermal conductivity of the soil, λgr, [W / m ∙ K] are set. Find the full heat transfer coefficient by the method of successive approximations and build a graph of the temperature drop along the length of the pipeline.
Initial data:
Build a schedule for replacing light product A with heavy B (option “a”) and heavy oil product B with light A (option “b”), if the length of the product pipeline is L = 200 km, 2 pump stations are located on the product pipeline (at “0” and “100” km ), Δz be taken equal to 0, do not take local resistance into account, the pressure of the booster pump should be taken equal to N final. At the NPS there were installed 2 working pumps of the НМ-440-300 brand (“a” of pump 452; “c” = 7400); the diameter of the product pipeline is 344 mm, the flow regime is the zone of the mixed law of resistance m = 0.123; β = 0.0075.
