Water at $65F$ and $20$ psia is mixed steadily with saturated water vapor at $20$ psia in an insulated chamber. Assume the chamber operates isobarically at $20$ psia and the kinetic and potential energies are negligible. If the cooler water is mixed with the hotter vapor with a mixing ratio of $2\mathrm{.}4($parts cold water per $1$ part vapor$),$ what is the quality of the exit stream?
