Stream Temperature
Stream Temperature
(OP)
Does anyone know if there is a way to calculate how much water is needed to be injected to a stream of a certain size to reduce temperature to a set level? If anyone has any ideas on how to approcah this subject it would be interesting too. This is just an idea we are throwing around and a little outside my expertise.
Thanks
Thanks

Something to keep in mind, when working in a "stream" environment or even using the term "stream", in conjunction with water temperature be cautious of how you combine the two terms. Stream, usually indicates that there is some kind of aquatic habitat present. Reducing water temperatures is generally accepted, however, increasing water temperatures in a stream are usually not.

(Combined T) = [(Stream Q)*(Stream T) + (Add Q)*(Add T)] / [(Stream Q)+(Add Q)]
..then solve for (Add Q)
I don't see why that wouldn't work. As others mentioned, best to ask the folks who do thermo for a living.
If you can't assume complete mixing, it gets horribly complicated. There are a number of other factors I'm neglecting which can also make this horribly complicated, such as sunlight warming, or pesky old hydrology.
I'm not an enviro guy, so I'm not sure what passes for acceptable practice in the field of effluent discharge. I'm just answering from a pure fluid mechs standpoint.
