A centrifugal air compressor has an inlet root diameter of 0.25 m and the outlet diameter of the impeller is 0.6 m. The pressure ratio is 5.0. The air at the inlet of the rotor is at 1 atm and 25 °C. The polytropic efficiency is 0.8 and the slip factor is 0.92. Use Cp = 1.004 kJ/kg-K and γ = 1.4. The impeller speed in revolutions per minute (RPM) is _______. (round off to the nearest integer)
Correct : 1
