2. Radial : At entrance to runner blade, velocity has primarily radial component. Eg: Old Francis turbines. Radial : At entrance to runner blade, velocity has primarily radial component. Eg: Old Francis turbines. Mixed : At entrance to runner blade, velocity has a radial as well as axial component. Eg: Modern Francis Turbines Mixed : At entrance to runner blade, velocity has a radial as well as axial component. Eg: Modern Francis Turbines Axial: At entrance to runner blade, velocity has primarily an axial component. Eg: Kaplan and propeller turbines. Axial: At entrance to runner blade, velocity has primarily an axial component. Eg: Kaplan and propeller turbines. Classification of Reaction Turbines: Radial, Mixed and Axial Radial Axial
