If I locate duplicate photos in the Photos database using Powerphotos, I would do so with the final objective of deleting them. However, if a duplicate is used in Photos as the master for a photo in an album will the photo in the album disappear if the duplicate is deleted?
No. What goes on in Photos stays only in Photos and the same goes for iPhoto.
My understanding of Powerphotos is that it will produce an album of duplicate photos. I assume that that will show up in Photos and it is from there that I would do the deletion. Does the album of duplicates not show up in Photos?
You're right. I you set PS's dup find preferences to add to an album you'll get this in the sidebar:
What I was referring to is that no matter what you delete from Photos it will not be deleted from iPhoto.
So, if I then delete the photos from there will photos disappear from my other albums if they had the deleted photos as masters? If that is the case I can't see a simple way to delete the duplicates without replacing the resultant delated photos in other albums -- Powerphotos shows that I apparently have over 2,000 duplicates which means replacing them one-at-a-time would be a laborious undertaking.

Yes. You'll have to determine which of the duplicates are those that are used in your various albums, books, etc. One way would be to make one set a favorite and check in the albums if the corresponding image has the favorite heart on the image:
Deleting Photos from a Photos Library
1 - regardless of where you are in the library, i.e. Moments, Collections, albums, smart albums or projects, select the photo(s) you want to delete and use the key combination of Command+Delete to move the photos to the Recently Deleted smart album.
2 - use the File ➙ Show Recently Deleted menu option to go to the Recently Deleted smart album.
3 - in the Recently Deleted album you can opt to let the photo automatically delete after the 30 day waiting period is up, delete them immediately or restore them to the library.
NOTE: deleting a photo from an album, slideshow, book, etc., with only the Delete key only deletes that photo from that item. Deleting a photo from a Moment or Collection deletes ALL occurences of that photo in the library.
Thanks very much for your help. I'll give the "favourites" option some thought
