According to the pressure gauge reading, the excess pressure in the closed tank Pizb = 4•106 N/m2. The pipeline axis is located at a depth h = 5 m from the free surface (Fig.). Local resistance coefficients of the shut-off valve Ecr = 4, nozzles Enozzles = 0.06. The linear resistance of the pipeline can be neglected. Determine the water flow Q if d1 = 10 cm; d2 = 20 cm; d3 = 8 cm.
