It is noted that the velocity profile has a significant effect on the temperature profile that develops in a fluid flowing through a tube. A numerical method for retrieving the velocity profile from a temperature profile is given and the computer program written to implement the method is described. The method retrieved velocity profiles of reasonable accuracy from temperature profiles calculated from the Graetz solution and by Kays’ numerical method. The results of a study to estimate the effects of possible experimental errors from several possible sources on the calculated velocity profiles are included.
