Three streams of water are mixed to obtain the feed to a separation process. Properties

of the feed streams and product of the mixing unit are as follows:

Feed stream $1$: $1kg{H}_{2}O\frac{1}{m}in$@$59C$

Feed stream $2$: $5kg{H}_{2}O\frac{1}{m}in$@$20C$

Feed stream $3$: $H_{2}O(1)$@$83C$

Product stream:

The mixing unit operates adiabatically. Draw and label the flowchart. Calculate the mass flow rates of

the feed stream $3$ and the product stream, neglecting potential and kinetic energy changes, using

tabulated enthalpy data in steam tables.
