The answer to this question is quite complex, and there isn't any one
formula that will give it to you. The rates at which fluids move through
pore networks depend on the sizes of the smaller openings in the pore
networks (the pore throats), the physicochemical characteristics of the
matrix material, the complexity of paths that the fluids must follow, and
the viscocity and surface characteristics of the fluids. This type of
question is usually studied empirically using capillary-pressure apparatus,
and a fair amount of data on chalks have been published in the technical
literature. You can do a search on capillary pressure, chalk, carbonate,
etc. in the database called GeoRef (see your nearest university science
library) and get many references. Some of the papers are probably online,
so a similar search of the Internet would probably be productive. I have
done a little research on capillary-pressure characteristics of chalks and
other carbonates myself (see references) and I can tell you that they vary
by orders of magnitude in their ability to transmit fluids. 

Movement of fluids through wood and ceramic involves the same issues, but
the details are very different, and I am not familiar with the literature
on these substances. And internet search might be a good way to start, and
the nearest materials sciences department at a university would probably
help with finding studies of ceramics.
