please help with this question. The answers are Stripping section= 9.8 ft Enriching section= 14.1ft Thank you.

D4.* A distillation column is separating a two-phase feed that is 60.0% liquid, 40.0mol% methanol, and 60.0mol% water. Distillate product is 92.0mol% methanol, and bottoms is 4.0mol% methanol. A total reboiler and a total condenser are used. Reflux is a saturated liquid. Operation is at 101.3kPa. Assume CMO, and use L/D=0.9. Under these conditions HG=1.3ft and HL=0.8ft in both the enriching and stripping sections. Determine the required heights of both the enriching and stripping sections. Equilibrium data are given in Table 2-7. Note: While HG and HL are the same for the enriching and stripping sections, L is NOT equal to Lbar, and V is NOT equal to Vbar. This means you will need to complete the material balances on the column to determine each of these quantities
