We now obtain a plot of the temperature distribution described by Equation (3.40) for = 1.724 x10-8 ohm, m, I = 100 amps, k = 401 W/mK , Ac = D2, D = 10mm, L = 1m, T0 = 293 K, TL = 373 K, Ta = 273 K, hD/hf=1.346, kf=0.0263 W/mK, V= 10 / D where = kinematic viscosity of the gas, m2 / s, and V = air velocity, m / s.
Now that we have obtained the temperature distribution in the rod Equation (3.40), the heat flux at any location is by Fourier's law.
