Let subscripts 1, 2, 3 denote rotor inlet, rotor outlet, and stator outlet respectively. For axial velocity constant ( C_x ) (free-vortex design assumed), the specific work input per stage is: [ \Delta h_0 = U (C_\theta 2 - C_\theta 1) ] where ( C_\theta ) is the tangential component. Using the change in relative tangential velocity: [ \Delta h_0 = U (W_\theta 1 - W_\theta 2) ]
