To quickly assess the difficulty of the text, read a short excerpt:
56; so that the 78 CENTRIFUGAL FAXS. theoretical area of the inlet or the product of the inlet area and its coefficient of discharge is 0. 56 n r 2 D 2 . 2 n2 ; = 0. 44 r 2 D 2 But from (23) we know that the blast area is 0. 44 r 3 D 2 . Therefore, the blast area, A, is equal to the theoretical inlet area multiplied by r\ and conversely, the theoretical inlet area is equal to * A the blast area divided by r, or J r. Effect of Outlet on Capacity. When the theo- retical outlet area of a fan, that... is the product of the area of the outlet multiplied by its proper coefficient of discharge, is less than the blast area, the pressure in the housing is that corresponding to the velocity of the tips of the floats; and the quantity of air discharged is equal to the velocity of the tips of the floats multiplied by the product of the area of the outlet and its coefficient of dis- charge. Let a be the area of the outlet, c its coefficient of discharge, and C x the number of cubic feet of air discharged per minute.
