Calculate the relative volatility for the multi component distillation using the Fenske equation

N = log [(LKd/HKd)(HKb/LKb)]/log( average)

N (number of trays) = 38

DON'T KNOW IF THIS MATTERS: average = sqrt[( LK, HK top of column)( LK, HK top of bottom)]

LKd = light key in distillate, HKd = heavy key in distillate, LKb = light key in bottoms, HKb = heavy key in bottoms
