2- A centrifugal compressor compresses air at atmospheric pressure of 1.013 bar and a temperature of 300K. The compressor has an angular velocity of 44,000 rpm, an impeller radius r = 50.8mm, an impeller thickness b=76 mm, and a tangential velocity Vi=180m/s. The blade angle B at the tip of the compressor vanes is 135º. Find: 1. The compression ratio P2/P1 2. The discharge pressure P2 3. The discharge temperature T2 4. The air density p2 , and; 5. The mass flow rate of air pumped by the compressor. Take for air k=1.4, cp= 1005 J/kg.K, and R=287 J/kg.K. (Value 15 points).
