Question:
A centrifugal blower rotates at 1400 rpm. Air enters the impeller normal to the blades (α1 = 0°) and exits at an angle of 25° (α2 = 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
