Two tanks containing water (tank A is closed, tank B is open and connected to the atmosphere) are connected using pipelines with diameters d1 = 70 mm and d2 = 100 mm and lengths l1 = 3 m and l2 = 5 m (Fig.). The difference in water levels in the tanks is H = 5 m. Let us assume that levels 1-1 and 5-5 remain constant. Determine the water consumption Q, if рм = 20 N/cm2 = 20•104 N/m2; L = 0.02; E2 = 0.5; e3 = (1 - d1|2/d2|2)2; e4 = 1.
