Anyone can help me ans Q-5? Question 6 A centrifugal compressor is required to deliver 8 kg/s of air with a stagnation pressure ratio of 4 rotating at 15,000 rpm. The air enters the compressor at 25°C an 1 bar. Assume that the air enters axially with velocity of 145 m/s and the slip factor is 0.89. The compressor isentropic efficiency is 0.89. Calculate: 4 the rise in stagnation temperature а) (6 marks) work input b) (2 marks) c) impeller...
