I'm doing a fun home project, and it involves water flowing through a metal pipe, where the surrounding is significantly lower temperature than the water in the pipe. The point of the exercise is to cool the water in the pipe as it flows through it.
The question is, what influence does flow speed have in the heat exchange? The extreme case is of course if it's flowing way too slow where the water is in equilibrium with the surrounding, meaning the overall heat transfer is impeded.
However, is there any downside to flowing too fast? My gut feeling is no, I suspect that from a certain speed on you transfer less heat per water volume, but it's offset by the increased transfer volume.
