The calculations inside and outside the pipe are different. I remember having answered this kind of question before; let me find it for you: http://bbs.hcbbs.com/viewthread.php?tid=419596&page=1#pid2248337. On page 12 of that link, there’s my response regarding the calculation of resistance
Relevant information can be found in standard heat exchanger design manuals, such as the \"Process Calculation Manual for Cooling Equipment\" compiled by Liu Wei and others; many such books are available for download on the Standard Sharing Network at www.bzfxw.com. There is definitely one that suits your needs
