The vaporization rate will be in kg/m^2.s, as it is for a given surface 
area, and the vapou pressure will be kPa. What are the 
parameters/properties that are needed to calculate the rate for a given 
temperature at normal atmospheric pressure? 

What I am looking
for is NOT a simple solution to this problem, but the detailed
proceedure through which the vapourisation rate of water may be
calculated, and its connection with the vapour pressure of water. NONE
of your archives seem to have this information, and I have been unable
to locate any site on the web that even gives me a satisfactory answer
to this query. Further more, the university library does not have any
details about this matter. Perhaps a rewording of the question may be in
order:

What is the proceedure/equation by which the diffusion of water into
atmosphere at SATP can be determnined, and what is its relation to
vapour pressure of water?

I do hope that you can help.

Yours faithfully,
