You wish to assess, approximately, the thermal conductivity λ of polyethylene (PE). To do so you block one end of a PE pipe with a wall thickness of x = 3 mm and diameter of 30 mm and fill it with boiling water while clutching the outside with your other hand. You note that the outer surface of the pipe first becomes appreciably hot at a time t ≈ 18 seconds after filling the inside with water. Use this information, plus data for specific heat C p and density rho of PE, to estimateλ for PE. How does your result compare with the listed value in the CES EduPack?
