A centrifugal fan rotates at a speed of 1460r/min and must deliver 1, 3m^3/s of air of density 1,22kg/m^3 at a total pressure of 370pa. Assume the manometric efficiency of the fan is 55% and that the whirl velocity at the exit of the impeller is double that of the peripheral velocity. Ignore mechanical losses and calculate a) the peripheral velocity of the impeller. b) the diameter of the impeller c) the power required to drive the fan
