A centrifugal compressor takes in ambient air at 100 kPa

1. A centrifugal compressor takes in ambient air at 100 kPa, 17â—¦C and discharges it at 450 kPa. The compressor has an isentropic efficiency of 80%. What is your best estimate for the discharge temperature?

2. A refrigerator uses carbon dioxide that is brought from 1 MPa, −20◦C to 6 MPa using 2 kW power input to the compressor with a flow rate of 0.02 kg/s. Find the compressor exit temperature and its isentropic efficiency.
