Consider a device that has one inlet with air flowing in at T$1=20$C$,$ p$1=200$ kPa, and two exit flows: one at T$2=0$C and the other at T$3=40$C$,$ both at $100$ kPa. The device op

erates at steady state with no external heat transfer or work and negligible kinetic and potential energy effects. Assume ideal gas with constant specific heats. Determine: a$.$ fraction of inlet flow that comes out at exit $2($m$2/$m$1)$ b$.$ is such a device possible
