Chapter 10 Boiling and Condensation 10-69 A 40-cm long cylindrical heat pipe dissipates heat at a rate of 150 W. The diameter and mass of a 40-cm long copper rod that can conduct heat at the same rate are to be determined. Assumptions Steady operating conditions exist. Properties The properties of copper at room temperature are ρ = 8950 kg/m 3 and k = 386 W/m. ° C. Analysis The rate of heat transfer through the copper rod can be expressed as
