Heat Exchanger Sizing Question 1

[Sam M]

Im looking to purchase a heat exchanger to cool oil in circulating lube oil system.
This will be cooled by the shop water line.

I had initially suggested these types.

https://www.mcmaster.com/heat-exchangers/heat-exchangers-5/heating-cooling-capacity~280000-btu-hr-/

Heat Capacity = 70HP/170,000 BTU
Oil Flow Rate = 21 GPM
Shop Water Flow Rate = 15 GPM
Water In = (60F - 90F)
Water Out = N/A (Water Will be Dumped out)
Oil In = 150F
Oil Out = 100F (Going Back into the system)

What is a good-sized heat exchanger for this application?

We seem to have lost the OP - last log in 8th Feb.

I would have liked to see some closure on this one.
