Analysis of Radial Flow Reaction Turbines (continued)

Vector diagram of velocities at entrance (1) and exit (2) of vane on impeller:

V = U + W where | U₁ | = r₁ ω and | U₂ | = r₂ ω

Note: The relative velocity diagrams are essential in the analysis of fluid motion on the impeller

since the transverse components of the absolute fluid velocity, V_t1 and V_t2 , need to be calculated.
