A layer of ethand 1mm deep lies at the bottom of an open tank 5m in diameter. The tank temperatuce is 298K and 1atm absolute presure. The density of ethanol is 0.78522g/cm3 and the diffusivity of ethand in air is 0.135cm2/s. The vapor pressure of ethanol in the tanKCan be defined as: log10P/mm1tg=8.04494222.65+71554.3 The diffusion maybe a ssumed to take place through a stagnant air film 3mm thick. ). Derive an equation to predict the flux of ethanol evaporation. ). Estimate the flux of ethanol at 298/K and total pressuce of 1 atm. ). Repeat part (ii) if the temperature increase to 330k. - Repeat paA (ii) if the total pressure increases to 3 atm. - Repeat part (ii) if the temperature and pressure inelease to 330 thand 3 atm, respecrivehy
