There is a centrifugal pump with a capacity of Q = 9000 l/s, consisting of suction and discharge pipelines. At the entrance to the suction pipeline with a diameter of d1 = 30 cm, the pressure is p1 = 200 mm Hg, in the discharge pipeline with a diameter of d2 = 20 cm, located at a height of z = 1.22 m above the axis of the suction pipeline, the pressure is p2 = 7 N/ cm2. Determine the hydraulic power of the pump.
