The melting temperature of the silicon is 1685 K. Assume a temperature of T[infinity]= 700 K in the ambient surrounding the sheets with a convective heat transfer coefficient of h= 10 W/m2·K. Assume that the width and the thickness of the sheets are 8.5 cm and 0.150 mm, respectively. What is the maximum velocity with which the sheet can be pulled out of the molten silicon? Assume all the energy released by solidification is dissipated by convection from the two sides of the sheet. Take the latent heat of fusion for silicon as hsf= 1.8 × 106 J/kg.
