1) You are given a 2-inch diameter cylinder of an unknown material and asked to determine its thermal conductivity. A thermocouple well is drilled into the material through one end at R/2, i.e., r = 0.5 inch. The thermocouple is installed, a recorder is connected, and the cylinder is plunged into a heated bath maintained at 200 F. It may be assumed that the initial temperature of the cylinder was a uniform 60 . In this manner, the following data are collected: T, S T(R/2), F 61 65 84 10 30 60 120 240 360 121 156 177 A) From this data, estimate the thermal conductivity, a in cm/s B) Make an educated guess as to the nature of this material C) Describe some potential limitations of the model or pitfalls of the analysis that would lead to an erroneous measurement of a. D) Offer an improved experimental procedure, if possible. 1) You are given a 2-inch diameter cylinder of an unknown material and asked to determine its thermal conductivity.
