However we are interested to solve problem from the begining
The current flowing through the wire can be calculated by: However we are interested to solve problem from
$\dot{Q}=h \pi D L(T_{s}-T_{\infty})$
$\dot{Q}=62.5 \times \pi \times 0.004 \times 2 \times (80-20)=100.53W$ However we are interested to solve problem from
