Determine the heat transport rate of energy through an animal skull where average inside surface temperature is 95 degrees farinhiet and whose out outside surface temperature is 90 F. Assume the skull is a spherical shell 7.5 inches in outside diameter and 0.25 inches thick.
Knowing; Thermal conductivity of this animal bone is = 0.25 Btu/h*ft. also knowing the conduction heat transfer based on Fourier's law = (Q)sphere = 4kt(ti-to)/(1/ri - 1/ro)
