Wien's displacement law

Students often get confused between Wien's displacement law and Planck's radiation law. Although both are historically related, yet they are conceptually different. Planck's law helps determine the spectrum of a blackbody, while Wien's law determines the relationship between peak wavelength and temperature.

Liquid helium is stored at its boiling-point temperature of 4.2 K in a spherical container (r = 0.30 m). The container is a perfect blackbody radiator. The container is surrounded by a spherical shield whose temperature is 91 K. A vacuum exists in the space between the container and the shield. The latent heat of vaporization for helium is 2.1 × 104 J/kg. What mass of liquid helium boils away through a venting valve in one hour?

You have a 5.3 inch diameter sphere heated to 335.0°F, which is inside of a large room with a surrounding temperature of Tsurr = 71.0°F. Treating the sphere as a blackbody, calculate the net heat transfer rate due to radiation between the sphere and its surrounds, in units of BTU/hr. The Stephan-Boltzmann Constant in English units is: σ = 1.714*10-9 BTU/(hr-ft2-°R4).
