dis- solved hydrogen

14.40    A  large  sheet  of  material  40 mm  thick  contains  dis- solved hydrogen (H2) having a uniform concentration of  3 kmol/m3.  The  sheet  is  exposed  to  a  fluid  stream that causes the concentration of the dissolved hydrogen to be reduced suddenly to zero at both surfaces. This surface  condition  is  maintained  constant  thereafter. If  the  mass  diffusivity  of  hydrogen  is  9 X 10-7  m2/s, how much time is required to bring the density of dis- solved hydrogen to a value of 1.2 kg/m3  at the center of the sheet?
