The following data pertains to a Centrifugal Compressor: Total pressure ratio=3.5:1 Diameter of the inlet eye of the compressor impeller= 34 cm. Axial velocity at inlet- 142 m/s Mass flow rate=12 Kg/s The velocity in the delivery duct=121 m/s The tip speed of the impeller-460 m/s Speed of the impeller- 16000 r.p.m. Total head isentropic efficiency = 80% Pressure coefficient -0.73 Ambient conditions: 1.013 bar and 15 C Calculate: 1) The static pressure and temperature at inlet and outlet of the Compressor. 2) The static pressure ratio 3) Work of the Compressor per Kg of Air 4) The theoretical power required.
