A thermocouple shielded by aluminum foil of emissivity 0.15 is used to measure the temperature of hot gases flowing in a duct whose walls are maintained at Tw = 320 K. The thermometer shows a temperature reading of Tth = 490 K. Assuming the emissivity of the thermocouple junction to be ε = 0.7 and the convection heat transfer coefficient to be h = 120 W/m2·K, determine the actual temperature of (he gas. What would the thermometer reading be if no radiation shield was used?
