💧 Centrifugal Pump Impeller: Velocity Triangles, Euler Head and Cavitation (2D)

Section through a backward-curved centrifugal impeller with its outlet velocity triangle. Change the speed, the diameter, the passage width, the blade angle, the number of blades, the discharge valve, the static head, the water temperature and the suction height, and see the Euler head with slip, the losses, the system curve, the operating point, the shaft power and whether the suction cavitates. The velocity triangle, the affinity laws, the energy balance and the vapour pressure are checked numerically, with four in-page numerical checks.
