The flow rate of an ideal liquid of relative density d = 0.860 in an expanding pipeline with diameters d1 = 480 mm (section 1-1) and d2 = 945 mm (section 2-2) is equal to Q = 0.18 m3/s (Fig. ). The difference in the positions of the center of the sections is 2 m. The pressure gauge reading in section 1-1 is p1 = 3•105 N/m2. Determine the fluid speed in sections 1-1 and 2-2; pressure p2 in section 2-2.
