A centrifugal compressor has an impeller tip speed of (U2=366 m/s) with inlet stagnation temperature (Toi=288K) and stagnation pressure (po1-100kPa). The flow leaving the radial blades (B2b = 90) of the impeller has radial component of velocity at impeller exit is (C2 = 30.5 m/s) and the slip factor is (u=0.9). Given that the flow area at impeller exit is (A2=r.d2.bz=0.1m?) and the isentropic efficiency of the impeller is 90%. Determine the exit Mach number (M2), stagnation pressure ratio (poz/po1) and the mass flow rate m For all problems the gas is air with Cp=1.005Kg/kg.K, R=0.287Kg/kg.K and y=Cp/Cv=1.4 Onestion #3 1 A centrifugal comupressor has an impeller tip speed of (U-366 m/s) with inlet staguation temperature (Tos 288K) and stagnation pressure (Por-100kPs) The flow leaving the radial blades (Bn- 90) of the umpeller has tadial cemponeat of velocity at inpeller exit is (C2 30.5 ms) and the slip factor is (r09).
