Hello, I am doing Dittus Boelter correlation for Nusselt number accroding to my measured data. Coefficient (or constant) M that is related to Re has (in my case) value of 1.12. Is it physically possible to get value greater than 1? In my previous research, I've only met with a value of less than 1, so I am little bit confused. Thanks for answer.

Thank you for your answer, I already found answer to my questions. According to Transport Phenomena by Bird Stewart Lightfoot is physically possible to obtain M constant value greater than 1. Unusual, but in some cases possible. I think that you refer to Pearson R correlation coefficient, which can have range but that is not case of Dittus-Boelter correlation.
