2.1 Cellophane is being used to wrap a food container to keep food moist at 38˚C. The cellophane is 3.28x10-4 ft thick, with an area of 2000 cm2. The vapour pressure of water vapour inside the container is 10 mm Hg and the air outside contains water vapour at a pressure of 5 mm Hg. The permeability of water vapour in cellophane is 1.82x10-7 liters solute (STP)/s. M2.Atm/m. 2.1.1 At steady state, calculate the flux of water vapor (kmol/s. M2)? (7) 2.1.2 Calculate the loss of water vapor in g/d at steady state?
