In Eqs. and (B6), an exponent

- 2 / 3

is missing from the square brackets, e.g., Eq. should read

T_{w} - T_{\infty} = A (x) \int_{0}^{x} {[1 - {(\frac{ξ}{x})}^{3 / 4}]}^{- 2 / 3} q_{w} (ξ) d ξ

(B4)

This typographical error does not carry into the results that follow.

In the last term of Eq. , the coefficients are incorrect. The correct expression is

\begin{matrix} {\bar{Nu}}_{L} \equiv \frac{\bar{h} L}{k} = 0.037 {Pr}^{0.6} ({Re}_{L}^{0.8} - {Re}_{u}^{0.8}) + 0.664 {Re}_{l}^{1 / 2} {Pr}^{1 / 3} \\ + \underset{contribution of transition region}{\underset{︸}{\frac{1}{c} (\underline{0.0296} {Re}_{u}^{0.8} {Pr}^{0.6} - \underline{0.332} {Re}_{l}^{1 / 2} {Pr}^{1 / 3})}} for gases \end{matrix}

(15)

where the changed numbers are underlined. As a result, Eq. should read

{\bar{Nu}}_{L} = \underset{turb .}{\underset{︸}{470.7}} + \underset{lam .}{\underset{︸}{221.6}} + \underset{trans .}{\underset{︸}{\underline{259.2}}} = \underline{951.2}

(16)

and the value 29.2% in the following line should be 27.2%.

No other result or conclusion of the paper is affected by these errors.
