A centrifugal blower rotates at 1400 rpm. Air enters the impeller normal to the blades (?1 = 0°) and exits at an angle of 25° (?2 = 25°). The inlet radius is r1 = 6.5 cm, and the inlet blade width b1 = 8.5 cm. The outlet radius and blade width are r2 = 12 cm and b2 = 4.5 cm, respectively. The volume flow rate is 0.22 m3 /s. What is the net head produced by this blower in meters of air? (a) 12.3 m (b) 3.9 m (c) 8.8 m (d) 5.4 m (e) 16.4 m
