Help with a formula

I am working to determine what the temperature loss (minimal at best) would be by mixing a stream of water flowing at 2,400 gph at 85 degree (f) into another stream of water flowing at 37,000 gph. Any help would be great

Do you mean you just need the final temperature of the mixture? That would be a weighted average of the two stream temperatures.

Yes the final temperature of the two stream the one at flowing 2,400 gph is 85 (f) and the one flowing at 37,000 gph is 105 (F).
