I guess one the general principles are the same as those for the calculation of the work function for slabs:

with the periodic direction of the nanotube being either along A or B.

Is it okay to do it for a unit nano tube (ring) or it has to be a large supercell?

yes, it is OK, the nanotube length does not matter.
