Question:

Performance curves [14] are given below for a centrifugal fan with D=36 in and N =600 rpm, as measured on a test stand using cool air ρ=0 075 lbm ft3 . Scale the data to predict the performance of a similar fan with D =42 in , N =1150 rpm, and ρ =0 045 lbm ft3. Estimate the delivery and power of the larger fan when it operates at a system pressure equivalent to 7.4 in. of H2O. Check the specific speed of the fan at the new operating point
