An air fan has a bladed rotor of 12 in outside diameter and 10 in inside diameter. The height of each rotor blade is a constant 1.0 in from blade inlet to blade outlet, that flowrate is steady on a time average basis. At 230 ft³/min and the absolute velocity of the air at blade inlet V1 is radial, The blade discharge angle is 30 ° from the tangential direction. If the rotor rotates at a constant speed of 1725 RPM estimate the power required to run the fan. (ans: 0.0972 hp)
