I have gathered experimental data regarding this heat transfer problem. Unfortunately right now there is no simple way to measure discharge water temperature.

On the theoretical approach developed on post # 10 of abovementioned thread, a water temperature increase of 50 °C was considered.

Please help me with the same numerical development, but now for a 25 °C water temperature increase.
Question: In this case, for the same steel considerations, the water flow is going to be twice as the one for 50 °C, which was 4.6 liters/sec? If not, what is going to be the amount of water flow?

Thanks.

Sorry, the thread number in the post doesn't link to anything related to heat transfer.

Please repost a valid link to your thread.

Here is the thread: https://www.physicsforums.com/showthread.php?t=304738

It's from 2009, so that's why it was closed (old threads are generally locked after a few years). I can merge this new thread back into the old one and unlock it all if folks think that's a better way to handle the new information.

Thank you, berkeman.

Indeed, it´s an old thread. Unfortunately in 2009 I had to deal with many other issues at work, and had to put the problem aside. But right now I´m involved again with the heat transfer problem, so I am asking for more help on the theoretical side.

Thank you for sharing your experimental data and the theoretical approach developed on post #10. It is great to see that you are continuing your work on this heat transfer problem.

Regarding the question about the water flow for a 25 °C temperature increase, it is not accurate to assume that the flow will be twice as much as the one for 50 °C. The amount of water flow depends on various factors such as the material properties of the steel, the geometry of the system, and the heat transfer coefficient.

To accurately determine the water flow for a 25 °C temperature increase, you can use the same numerical development approach as in post #10, but with the new temperature difference of 25 °C. You can also consider using a heat transfer calculator or simulation software to get a more precise result.

I would also suggest conducting further experiments to validate your theoretical approach and to gather more data points for different temperature differences. This will help to improve the accuracy of your numerical development and provide a better understanding of the heat transfer problem.

Good luck with your research!
