What should we consider for the PSV outlet temperature and pressure when sizing psv tailpipe.

Can we consider and isoenthalpic flash from relieving temperature & pressure to the backpressure at psv outlet? what would be reasonable assumption? what is criteria for psv tailpipe sizing

while you can estimate pressures from dp calcs in tailpipe, temperatures are (normally) below values predicted solving a H-P flash operation, see this thread

there are several procedures available and you can estimate a range of temperatures with software tools (see the thread for details),

I do not know if there is an accepted standard discussing this detail (apart the general discussion in API, ISO etc.)
