Solution:

The heat transfer from the insulated pipe is given by: Solution: The heat transfer from the insulated pipe

$\dot{Q}=10 \times \pi \times 0.08 \times 5 \times (150-20)=3719W$ Solution: The heat transfer from the insulated pipe

$r_{o}+t=0.04+0.02=0.06m$

$\dot{Q}=62.5 \times \pi \times 0.004 \times 2 \times (80-20)=100.53W$ Solution: The heat transfer from the insulated pipe

The convective heat transfer coefficient can be obtained from:

$\dot{Q} {conv}=h A(T {skin}-T_{\infty})$
