An upward flow in a vertical circular pipe at atmospheric conditions is considered. The constants in the correlation have been obtained after 2800 measurements. The accuracy of correlation is found to be 96.5 using t test. Delta T-h(tp) and h(tp) variations are also investigated using measured data.eninfo:eu-repo/semantics/closedAccessConference Object345348WOS:000080610100068N/A
