Let W= work done per kg of steam;

$C_i \text{= Absolute velocity of steam at inlet to moving blades;} \\ C_0\text{=Absolute velocity of steam at exit to moving blades;} \\ C_{wi}\text{=Tangential component of Ci called as velocity of whirl at the inlet to moving blades, m/s} \\ C_{wo}\text{=Velocity of whirl …
