An axial flow turbine operates with a constant axial velocity throughout of 230. The rotation speed is 3600rpm and the mean radius is constant at 1.2m. It is designed with repeating stages and the entry velocity of each stage is purely in the axial direction. The absolute flow angle at exit from the stator is 35 degrees If the velocity is purely in the axial direction, why is there a flow angle? If the flow at entry of the rotor is angled why isnt the flow angled at the exit of the rotor? Thanks
