Air is compressed in a steady-state, insulated flow device. The air enters at 1 bar, 25 C

Question:

Air is compressed in a steady-state, insulated flow device. The air enters at 1 bar, 25 °C and exits at 5 bar, 200 °C.

a) Determine the amount of work needed for this compression.

b) Calculate the entropy generation.

c) What is the minimum amount of work necessary to compress air from 1 bar, 25 °C to 5 bar?

d) What would be the temperature at the exit of the compressor in part (c)?

Assume air to be an ideal gas with C_p = 30 J/molK.
