5. A spherical thermocouple bead of diameter D = 0.002 m (i.e. 2 mm) on the tip of a wire is used to measure tempera- ture of a low-speed, hot gas flow in a duct (Fig. 2). The gas' approach speed is U. = 2 m/sec and its respective density and viscosity are p = 1 kg/m3 and v = 2 x 10-5 m2/s. The coefficient of drag for such moderate flows is well- approximated by the curve fit Cp...
