Task 41 Centrifugal pump 1

Task 41 Centrifugal pump 1 supplies water with a temperature t = 10 °C. The water consumption is Q = 5L/s. The diameter of the suction tube d = 75mm, length L = 15m. Pipe 2 has two 90° rotations and a receiving valve 3. The pipe material is new welded steel, the pressure on the free surface of the liquid is 100 kN/m2. Determine the maximum possible height of the pump installation above the water level, based on the condition that the water pressure at the pump inlet should be 20 kN/m higher than the vaporization pressure
