Okay, so for the first question, it wants us to do a degree of freedom analysis to show that the problem statement is correctly defined.
00:15
So the degree of freedom calculation, we know the number of unknowns is f1 is 1 ,000, f2 is 1 ,200, f of b -a -s -o -4 is 1 ,000, and then f of h -c -l -o -4 is unknown.
00:40
And so there are two equations because of this.
01:01
So equation one is f1 is equal to f -b -a -s -o -4 plus f -h -c -l -o -4 divided by 2.
01:21
And then equation 2 is f -2 is equal to f -h -c -l -o -4.
01:30
For the second question, the moles of product h -c -l -o -4 leaving per mole, of feedstream 1, we have f -h -c -l -o -4 over f -1 as equivalent to 1 ,200 over 1 ,000, which gives you 1 .2 moles of h -c -l -o -4 per of b -a -c -l -o -4 -2.
02:10
And for the third question, the single -pass conversion, we have f -1 is equal to f -b -a -s -o -4 plus f -h -c -l -o -4 divided by two...
