Given below are performance curves for a centrifugal fan with D=914 mm and ω=600 rev/min, as measured on a test stand using air at ρ=1.20 kg/m³. Scale the data to predict the performance of a similar fan with D’=1070 mm, ω’=1150 rev/min, and ρ’=0.72 kg/m³. Estimate the delivery and power of the largest fan when it operates at a system pressure equivalent to 190 mm of H₂O. Check the specific speed of the fan at the new operating point.
