Stream Temperature Alteration

[martin888888]

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

What is the stream that you're cooling? Is it water as well? If so then the arithmetic is pretty simple algebra. So much mass at T1, so much mass added at T2, result is at T3, it's just a weighted average as long as there is no phase change (if anything boils or freezes then you need to do an energy balance).

You gotta have a buddy somewhere that is an ME or a ChE. This is a pretty simple first law (of Thermodynamics) calculation and they could do it for you out of hand.
