A liquid feed of 100kmol/hr is fed to a distillation tower operating at 405.3 kPa. The composition in mole fractions is as follows: n-butane (xA = 0.40), n-pentane (xB = 0.25), n-hexane (xc = 0.20), n-heptane (xD = 0.15).the feed is fractionioned such that 90% of pentane is to be recovered in the distillate and 90% of hexane is recovered in the bottoms  what are the vapor and liquid flow rates of the resulting stream
