| Abstract: | This paper presents the quantitative estimating formular of starting length for thermal entrance in pipes. Moreover defeloping temperature distribution function T (x, r ) in pipes satisfied with differential equation for arbitrary prandtl' s number are established. Finally some Corresponding particular cases are caculated numerically. |
