Subtopic: Steady state heat transfer in conduction, convection and radiation
Question Statement:
Milk flows turbulently through a stainless steel tube of inner diameter $D = 0.025\text{ m}$ in a tubular pasteurizer. The Reynolds number is $Re = 10000$, Prandtl number is $Pr = 4.0$, and thermal conductivity of milk is $k = 0.58\text{ W/(m}\cdot\text{K)}$. Using the Dittus-Boelter heating correlation $Nu = 0.023 Re^{0.8} Pr^{0.4}$, the convective heat transfer coefficient $h$ inside the tube in $\text{W/(m}^2\cdot\text{K)}$ is ________ (round off to 1 decimal place).
