Depends if you do schedule 40 or schedule 80 bulkheads because the wall thickness is different, but the typical black bulkheads are schedule 40 (schedule 80 is grey usually).
For schedule 40 this is what I think I know:
For a 1" bulkhead the hole required is 1-3/4".
1.5" needs 2 - 3/8"
2" needs 3"
3/4" needs 1 - 1/2"
