1. Calculate the heat (in watts) entering the rod at z = 0 and that leaving at z = L for the problem with heat loss at the periphery. T1 = 293 K, T2 = 373 K, Ta = 273 K, I = 100 amps, = 1.724 x 10-8ohm m, D = 10 mm, kf = 0.0263 W/m K, hD/kf = 1.346 for k = 401 W/ m K, V = 10v/D where v = kinematic viscosity of the fluid and V = air velocity.
