Question: An inventor claims to have designed a flow device which gives equal amounts of cold air at 2 5 0 K and hot air at

An inventor claims to have designed a flow device which gives equal amounts of cold air at 250 K and hot air at 350 K at 1 bar pressure when the device is fed with air at 30 bar and 300 K . He further claims that the device does not require any energy input to operate. Treat the air is an ideal gas with =1.4. Judge whether such device is thermodynamically possible or not.
