Analysis of single$-$step processes$-$Assume kinetic and potential energy changes are negligible.

d$)$ A continuously operating, adiabatic flow process combines liquid methane at $1$MPa and $120K$

with gaseous methane at room temperature $(300K)$ and $1$MPa. Determine the flow rates of

the two streams needed to output of $1k\frac{g}{s}$ of saturated methane vapor at $1$MPa.

e$)$ If the two input streams flowed into the above process with the same mass flow rates,

determine the output temperature and its phase$($s$)/$composition$.$
