Mechanical Engineering

An axial flow fan has a hub diameter of 1.50 m and a tipdiameter of 2.0 m. It rotates at 18 rad/s and when handling5.0?^(3)s^(-1) of air, develops atheoretical head equivalent to 17mm of water. Determine the bladeoutlet and inlet angles at the hub and the tip. Assume that thevelocity of flow is independent of radius and that the energytransfer per unit length of blade is constant. Assume density ofair is1.2 kg/m^3
