Apackage is made of three ears of corn by placing them on a styrofoam tray and enclosing them with plastic wrap. the exposed area is 500 cm2. it is desired to keep moisture losses below 1% of the total water content estimated at 100 g per package for a shelf life of 2 weeks. assume the diffusivity of water vapor through the plastic wrap is 2.0 × 10-4 cm2/s and a constant internal saturation vapor pressure of 23.8 mmhg (25oc) and zero external moisture. what thickness of wrapping is needed to fulfill this requirement? is this reasonable? if not, what could you do to try to fulfill the requirement?
