Question 5 A centrifugal blower rotates at 1750 rpm (183.3 rad/s). Air enters the impeller normal to the blades (0) and exits at an angle of 40 from radial (40%). The inlet radius is r = 4.0 cm, and the inlet blade width bi 5.2 cm. The outlet radius is r2 = 8.0 cm, and the outlet blade width b2 = 2.3 cm. The volume flow rate is 0.13 m/s. For the idealized case, i.e., 100 percent efficiency, calculate the net head produced by this blower in equivalent millimeters of water column height. Also calculate the required brake horsepower in watts
