Solution Manual Heat And Mass Transfer Cengel 5th — Edition Chapter 3

The heat transfer from the insulated pipe is given by:

$Nu_{D}=CRe_{D}^{m}Pr^{n}$

Assuming $h=10W/m^{2}K$,

$\dot{Q}=h A(T_{s}-T_{\infty})$

Assuming $\varepsilon=1$ and $T_{sur}=293K$, The heat transfer from the insulated pipe is
