Two AISI 304 stainless steel plates 10 mm thick are subjected to a contact pressure of 1 bar under vacuum conditions for which there is an overall temperature drop of 100℃ across the plate. (a) What is the heat flux through the plates? (b) What is the temperature drop across the contact plane? Use R"ₜ, = 15 x 10⁻⁴ m². K/W and evaluate the properties of stainless steel at 400 K.
A. q" = _______ W/m²
B. ∆T = ________ ℃
