For a given flash separation of methanol $(1)$ and ethanol $(2)($different conditions than in Problem $1),$ it is determined that V$/$F $=0\mathrm{.}62,$ x$1=0\mathrm{.}523,$ y$1=0\mathrm{.}648,$ T $=75$ oC$,$ and Pdrum $=121\mathrm{.}0$ kPa. For these conditions and a feed flow rate of $800$ kg moles$/$hr$,$ find the dimensions of a flash drum in feet for the case where htotal$/$D $=4\mathrm{.}5.$ To calculate vapor densities, assume the vapor is an ideal gas. The molecular weights for methanol $(1)$ and ethanol $(2)$ are $32\mathrm{.}042$ and $46\mathrm{.}069,$ respectively. The estimated liquid density for the liquid product at $75$ oC is $738\mathrm{.}3$kg$/$m$3.$
