Combustion gases flow from a stator of an axial turbine with absolute speed V 2 = 500 m/s at angle a 2 = 67?. The relative velocity is at an angle ß 2 = 30? as it enters the rotor and at ß 3 = -65? as it leaves the rotor. (a) Find the utilization factor and (b) the reaction. Assume the axial velocity to be constant.
