A system of two pipelines connected in series d1 = 100 mm and d2 = 200 mm, l1 = 200 m and l2 = 300 m connects tanks A and B, which have free surfaces at levels H1 = 100 m and h2 = 200 m (Fig.). Loss coefficients due to local resistance: E1 = 0.5; E2 = 0.1; e3 = 0.6; coefficient of friction on linear resistance for the formed turbulent regime [1, p. 61] L = 0.02 + 0.5/d. Determine the fluid flow between the tanks.
