Two streams are mixed in an adiabatic mixer, as shown in the figure. It is known

that:

Stream $1$ is saturated liquid$/$saturated vapour mixture at $1$ bar with flow rate

$0\mathrm{.}94k\frac{g}{s}$ and quality $0\mathrm{.}19$

Stream $2$ is superheated vapour at $1$ bar and $495C$

Stream $3,$ the product stream, is a saturated liquid$/$saturated vapour mixture

at $1$ bar with quality $0\mathrm{.}83$

Neglect kinetic and potential energy changes and calculate the mass flow rate of the

superheated vapour stream, in $k\frac{g}{s}.$
