PLEASE SOLVE WITH CLEAR WRITING AND DETAILS

DON'T COPY THE SOLUTION ALREADY SOLVED IN CHEGG BUT I THINK THE SOLUTION IS INCORRECT.

PLEASE SOLVE IT AND EXPLAIN HOW TO USE THE RATIO: X= m^3 of solvent/m^3 of feed

***IF YOU RE SEND THE SAME SOLUTION ON CHEGG I WILL DISLIKE!***

Q2) 50m3/ day feed enters a plate column using an extraction process. The allowolite velocity per square meter of cross-sectional column area is 12.2m3 of combined solvent and feed per hour. The costs for the installed equipment FX can be prediched by FX=9000X250,000x+100,0005/yr where X is the cubic meters of solvent per cubie meter of feed. The cost of each cubie meter of solvent entering the column is $1.50. It is required to operate at minimum total cost per year. Take 300 day in the year. Estimate at optimum conditions a) Cubie meters of solvent per cubic meter of feed, X b) Fixed capital cost d) Colunnal operating cost Hint Atlowavle vetocity, hrm=Crosssectionataream2feedrate(1+X)hrm3
