$r_{o}=0.04m$
(b) Convection:
The heat transfer due to convection is given by: $r_{o}=0
$\dot{Q}=h \pi D L(T_{s}-T
$\dot{Q}=\frac{V^{2}}{R}=\frac{I^{2}R}{R}=I^{2}R$ $r_{o}=0
The convective heat transfer coefficient for a cylinder can be obtained from:
The Nusselt number can be calculated by: $r_{o}=0
$\dot{Q} {net}=\dot{Q} {conv}+\dot{Q} {rad}+\dot{Q} {evap}$
