A radial fan is used to circulate fresh air (p = 1.20 kg/m) through a building. The fan operates at = 4000 rpm, has a volume flow rate of 0.8 m/s, and requires 2 kW to run. The blade geometry is given by r = 14 cm, r = 20 cm, b = 4 cm, b = 5 cm. The inlet flow angle is = 0. a) Determine the inlet and outlet flow angles, and 2. b) Draw the velocity triangles for the inlet and the outlet.
