📌 PROBLEM 19-23 . - A centrifugal pump rotates at 750 RPM. The geodetic difference in level between the suction and discharge tanks, open to the atmosphere, together with all the pressure losses external to the pump amounts to 15m. The angle 𝜷_𝟐=𝟒𝟓°. The average velocity of the water in the pipes, as well as the meridional velocity inside the pump, remains constant and equal to 2m/s. The flow inlet into the blades is radial. The manometric efficiency of the pump is 75%. Width of the impeller at the outlet 15mm. Calculate: a) External diameter of the impeller; b) Dynamic height of the impeller to be transformed into pressure head in the spiral casing; c) If the diameter of the impeller at the inlet is 0.4 the diameter of the impeller at the outlet, calculate the flow rate and the width of the impeller at the inlet; d) 𝜷_𝟏; e) Pump performance, if 𝜼_𝒎=𝟎.𝟗 and 𝜼_𝒗=𝟏 #HydraulicMachinesCourse ✅ Personalized advice → https://wa.link/eckmlw 📚 Chapter No. 19 From the book by Claudio Mataix 2nd edition - ROTODYNAMIC PUMPS 💥Course on Strength of Materials (From Scratch) • MECHANICS OF MATERIALS - Equilibrium of... 💥Static Exercises • STATICS Taking as reference the bibliographies of: Hydraulic Machines by Claudio Mataix 2nd Edition Hydraulic Turbomachines by Polo Encinas 2nd Edition 💥 Leave your beautiful like👍, Subscribe👆 and Share💪.
