Problem 2. For a given flash separation of ethanol (1) and 1-propanol (2) (different conditions than in Problem 1), it is determined that V/F = 0.599, X1 = 0.495, y1 = 0.670, T = 90 C, and Parum = 117.5 kPa. For these conditions and a feed flow rate of 1200 kg moles/hr, find the dimensions of a flash drum in feet for the case where hota/D = 4.0. To calculate vapor densities, assume the vapor is an ideal gas. The molecular weights for ethanol and 1-propanol are 46.069 and 60.096, respectively. The estimated liquid densities for ethanol and 1-propanol at 90 C are 725.0 and 739 kg/m, respectively
