Steam Boilers, Engines, Nozzles and Turbines In a Parson's turbine stage, blade velocity is 320 m/s at the mean radius and rotor blade exit angle is 30°. For minimum kinetic energy of the steam leaving the stage, the steam velocity at the exit of the rotor will be 640/3 m/s 160/3 m/s 320/3 m/s 640 m/s 640/3 m/s 160/3 m/s 320/3 m/s 640 m/s ANSWER DOWNLOAD EXAMIANS APP
