The temperature of a flowing gas is to be measured with
a) thermocouple junction and wire stretched between two legs of a sting, a wind tunnel test fixture. The junc- tion is formed by butt-welding two wires of different material, as shown in the schematic. For wires of diame- ter D = 125 µ,m and a convection coefficient of h = 700 W/m2 · K, determine the minimum separation
film (-w1/2 x +w1/2).
(b) If the heat flux provided by the laser is 10,000 W/m2, determine the temperature of the plastic film at the center (x = 0) and its edges (x = ±w1/2).
(c) Plot the temperature distribution for the entire strip and point out its special features.
