In order to enhance net radiation exchange between a high temperature surface and a low temperature surface in an enclosure, one should:. (A) polish both surfaces so that they are highly reflective
(B) paint both surfaces so that they are close to a blackbody surface

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
