Thanks for the reply.
So, as I see it, so far I've worked out the decrease in the entropy of the rivet.
The heat flowing into the reservoir from the rivet cooling will be the same as the heat loss from the rivet:
That gives me 17250 J.
Then, if we assume the temperature of the...

A shipyard worker drops a hot steel rivet (mass 125g, temperature 350 degrees C)
into a river at temperature 5 degrees C, a distance 30m below. Stating any assumptions
you make, calculate the entropy change of the universe as a result of this event.
