polar alignment error as number of pixels in a CCD.

Can anyone provide an equation relating polar alignment ierror in
minutes of arc to number of pixels in a CCD camera, knowing the
focal length of the telescope in use and the pixel size in microns
assuming normal siderial rotation E to W about the RA axis with Dec
perpenndicular to the RA axis for a given period of time in minutes ?
Thanks - Gerald.
