The shaft of small axial flow turbine turns at 25000 rpm, and the blade speed is U= 250m/s. The axial velocity of the fluid leaving the stator is V a1

= 175 m/s. The angle at which the absolute velocity leaves the stator blades is a, = 67°, the blade angle of the rotor is B2=-60°, and the absolute velocity leaves the rotor at the angle A2 = - 20°, Find the following. Draw velocity diagram at the inlet and outlet. The mean radius of the blades, The angle of the relative velocity entering the rotor, The magnitude of the axial velocity leaving the rotor. The magnitude of the absolute velocity leaving the rotor. The specific work delivered by the stage.
