WebIn a Parson's turbine stage, blade velocity is 320 $\mathrm{m} / \mathrm{s}$ at the mean radius and the rotor blade exit angle is $30^{\circ} .$ For minimum kinetic energy of the steam leaving the stage, the steam velocity at the exit of the stator will be ... If 'D' is the diameter of the turbine wheel and 'U' is its peripheral velocity, then ... When the pressure drop available is large, it cannot all be used in one turbine stage. A single-stage utilizing a large pressure drop will have an impractically high peripheral speed of its rotor. This would lead to either a larger diameter or a very high rotational speed. Therefore, machines with large pressure drops employ more than one stage.
