1- Consider a plane wall, 15 cm in thickness, made of stainless steel (SS304) in which the heat transfer is one dimensional (axial direction-x, with the origin at the left wall). The left end of the wall is maintained at 573 K, and the right end is at 373 K. The thermal conductivity of the material is known to vary as: k = 16.5 + 0.0175(T – 373) where T is the temperature in Kelvin and k is in W/mK. a. Determine the heat transfer rate across the wall under steady state conditions.

1.63 Liquid oxygen (LOX) for the space shuttle is stored at 90 K prior to launch in a spherical container 4 m in diameter. To reduce the loss of oxygen, the sphere is insulated with superinsulation developed at the U.S. National Institute of Standards and Technology's Cryogenic Division; the superinsulation has an effective thermal conductivity of 0.00012 W/m K.
