There is a centrifugal water pump installation in which there is a height from the well suction to the pump shaft of 4m and from the pump shaft to the upper level of the tank drive tank 56m. The suction and delivery pipes are Ф150 mm. The pressure loss in the suction pipe amounts to 2m and in the delivery pipe (not including losses at the exit and entrance of the tank) is 7m. The impeller dimensions are: D2 = 400mm; b2 = 25mm; β2 = 30°. The pump rotates at 1450 rpm. The entry into the blades is radial. The hydraulic performance is ηh = 82%. Neglect the influence of the thickness of the blades. Calculate:
a) The Flow;
b) The water pressure next to the suction flange;
c) The water pressure next to the delivery pipe flange.
