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

Question
Can you draw a diagram of what’s happening please thanks
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
