A thermocouple inserted in a 4-mm-diameter stainless steel tube having a diffuse, gray surface with an emissivity

Question:

A thermocouple inserted in a 4-mm-diameter stainless steel tube having a diffuse, gray surface with an emissivity of 0.4 is positioned horizontally in a large airconditioned room whose walls and air temperature are 30 and 20°C, respectively.

(a) What temperature will the thermocouple indicate if the air is quiescent?

(b) Compute and plot the thermocouple measurement error as a function of the surface emissivity for 0.1 < ɛ < 1.0.
