Low emissivity (low e or low thermal emissivity) refers to a surface condition that emits low levels of radiant thermal (heat) energy. All materials absorb, reflect and emit radiant energy according to Planck\'s law but here, the primary concern is a special wavelength interval of radiant energy, namely thermal radiation of materials.

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 T w 320 K. The thermometer shows a temperature reading of T th 490 K. Assuming the emissivity of the thermocouple junction to be 0.7 and the convection heat transfer coefficient to be h K, determine the actual
