The measured specific energy required for the evaporation of zirconium is reported to be 61.5 kW-h/kg. If the metal was electron-beam melted in a 100-mm-diameter water-cooled copper crucible, how does this energy compare with that predicted in the text? Assume the thermal conductivity of Zr is 30 W/K-m, and the average charge thickness is 1 cm.
