Air with a velocity of 40 m/s enters an adiabatic compressor through a 4-cm-diameter pipe at 100

Question:

Air with a velocity of 40 m/s enters an adiabatic compressor through a 4-cm-diameter pipe at 100 kPa and 30°C and is compressed to 2000 kPa. Determine the power required if
a) The air exits at 450°C
b) An adiabatic, quasi-equilibrium process is experienced by the air.
