Draw the velocity triangles at the inlet and outlet sections of a centrifugal pump whose impeller curvature is in the clockwise direction and the impeller is rotating in the counterclockwise direction. Assume no swirl flow at the inlet. ii) Figure 2 shows a typical cross-section of a working Francis turbine. The turbine consists of four main parts namely stationary/stay vanes, wicket/adjustable vanes, rotary vanes (impeller), and draft tube. Discuss the purpose and advantages of each component.
