1. How long does it take to make a 1 m3 sealed container 12g/m3 to 16g/m3 as shown below? Initial concentration change rate dC/dt = 1 g/m3 /sec
2.
Fiber specimen containing 1 X 10-3 g of water in an open bowl in the (+) x axis direction as shown below. The diffusion of moisture during drying of this specimen takes place only in the direction of the x-axis. The concentration is C= a – x2 (a: constant). How many seconds does it take for this fiber to dry completely?
where D = 1 X 10-8 cm2/sec. And what are the assumptions for this calculation ?
