Problem #$12$

Situation:

Superheated steam at $10[$bar$]($stream $1)$ is mixed with saturated steam at $7\mathrm{.}5[$bar$]($stream $2)$ in a $2$:$1$ ratio of stream $1$ per $kg$ of stream $2).$ The product stream $(3)$ is at $250[C]$ and $7\mathrm{.}5[$bar$].$ The process is adiabatic and at steady state.

Requirements $($state any assumptions$)$:

Please, based on the information above, do the following:

$($a$)$ Draw a diagram of the process.

$($b$)$ Indicate the state of stream $3($vapor or liquid, saturated or not$).$

$($c$)$ Determine the temperatures of stream $1$ and stream $2,$ in $C.$
