Question
A porous membrane having a width of 1cm, contains A at a concentration of 0.5 kmol/m³. One
side of the membrane is suddenly exposed to gas and concentration of A at this side is increased
to 2 kmol/m³. Calculate the concentration values by finite differences method using computer
programing and below data.
Calculate the time it takes for the concentration of A to be 2 kmol/m3 everywhere in the
membrane.
Ox=0.0025m (5 space)
Ot=0.01s
