QUESTION 5 [12] An Axial flow fan has to supply air to an office block. The 18 blade stator is located upstream from the rotor and deflects the air 30° as to allow for corrected flow through the rotor. The air

stream has a velocity of 35 m/s, the rotor rotates at 2000rpm and the air stream leaves the rotor axially. At a radius of 0.6m calculate: 5.1. The leading edge angle of the rotor. The trailing edge angle of the rotor. 5.2. (6) 5.3. How many blades should there be on the rotor? (2)
