Problem 7: Consider a medium in which the heat conduction equation are given in its simplest form as r 1 a (i)+2=0; (ii) (120) dr (a) Is heat transfer steady or transient? 1 dT == (b) Is heat transfer one-, two-, or three-dimensional? (c) Is there heat generation in the medium? (d) Is the thermal conductivity of the medium constant or variable? (e) How many boundary conditions are required to obtain solution?
