Weband V1 sinα = V1 sin90 = V1. This is flow velocity, hence, ‘Vf1 = V1. In the same way, at the outlet, absolute velocity V2 also will have two components, Vertical component, Vf2, this is flow velocity at the outlet. Horizontal component, Vw2, this is whirl velocity at the outlet. In this way, the triangle at the outlet is completed
