An isentropic compressor that takes in air from the atmosphere at 100 kPa and 300 K compresses it to 1 MPa. The compressor feeds into a rigid tank that is initially filled with 5 kg of air at a pressure of 500 kPa and a temperature of 500 K. Once the mass in the tank reaches 8 kg, the compressor will stop to prevent the tank from rupturing, which will occur if the pressure exceeds 1000 kPa.
a) Determine the work needed to drive the compressor during the
process.
b) What’s the final pressure in the tank? Will it rupture?
c) What’s the entropy generated during this process?
