If the water activity of chicken meats with a surface area of 30 cm and stored at 20 C at 1 atm pressure and 40% relative humidity is 0.95, calculate the mass transfer flux of water moving away from the surface of the chickens, taking into account the 4 cm mass transfer film thickness. How much weight do chickens lose to 8 cm of surface area after 1 day of storage? (MASU=18 kmol/kg). urgenttttttt please
