(a)Air, which can be assumed to behave as an ideal gas,
undergoes a process from 150kPa and 400K to 600kPa and 500K within
a piston cylinder. Can this process occur adiabatically? (Think
about what the limitations on ???? are to answer this question).
(b)Now consider air which is compressed in an air compressor
adiabatically from 150kPa and 400K to 1000K and 600kPa. It enters
the air compressor with a mass flow rate of 1kg/s. Determine the
rate of entropy produced...
