Water at atmospheric pressure and 300 K mean temperature is flowing in a hydraulically smooth tube that is 0.08 m in diameter. Assume UWT boundary condition with tube inner surface temperature at 360 K. Assume that the flow is thermally developed.

a. For Re_D
= 10⁴
, 5 × 10⁴
, and 105 calculate the convective heat transfer coefficient using the analogy of Yu et al. (2001) (Equations 9.6.6 through 9.6.10).

b. Repeat the solutions of Part a, this time using Equation 7.4.20 for calculation of turbulent Prandtl number, instead of Equation 9.6.8.

Discuss the results.
