Assignment $02$

A large supply line has a steady flow of R$-410$a at $\backslash (1000\backslash$mathrm$\{$kPa$\},60\backslash$mathrm$\{$C$\}\backslash ).$ It is used in three different adiabatic devices shown in the Figure: a throttle flow, an ideal nozzle, and an ideal turbine. All the exit flows are at $300$ kPa $.$ Find the exit temperature and specific entropy generation for each device and the exit velocity of the nozzle.
