Problem $1$ A stream of liquid $1$ at $300K$ with a flow rate of $2mo\frac{l}{s}$ and a stream of

liquid $2$ at $340K$ with a flow rate of $3mo\frac{l}{s}$ are mixed in an adiabatic mixer in a steady

flow process. The molar excess Gibbs energy of the mixture is represented by

$G_{{?}^{?}}(ex)=1500x_1{x}_2$

a$)$ Estimate the temperature of the stream exiting the mixer if the heat capacities

for pure components $1$ and $2$ are $40\frac{J}{m}ol.K$ and $60\frac{J}{m}ol.$K$,$ respectively.

b$)$ Determine the rate of entropy change as a result of the mixing process.Problem $1$ A stream of liquid $1$ at $300$ K with a flow rate of $2$ mol$/$s and a stream of liquid $2$ at $340$ K with a flow rate of $3$ mol$/$s are mixed in an adiabatic mixer in a steady flow process.
