Question $4$

Three gas streams are mixed to produce a product stream. The molar compositions are as

follows:

a$)$ Draw a flowchart for the process.

b$)$ Do a degree$-$of$-$freedom analysis taking a basis for the product stream as $100mo\frac{l}{s}.$

c$)$ Find the molar flow rates of the three input streams. Show all calculation steps.

d$)$ If it is desired to have the flowrate of stream $1$ to be $500$lbmo$\frac{l}{h},$ what will the flowrates

of the other streams?
