Water wheel power generation

Good day.
Can anybody please help me with the following.
we have a 6m diameter water wheel that we can feed 112 litres per second. It turns at 16 rpm when free running with no load. With the gearing we have done it goes up to 160 rpm.
the bucket can carry 120 litres
What will the torque be and the  potential power generation be on this water wheel.
see attached a picture.

Backwoods Home magazine wrote a very useful and accessible article a while back.  Here you go:

Borst engineering has an interactive worksheet that accounts for, I think...everything.  I haven't worked it, but casual inspection suggests this will yield useful and accurate estimates.
