Silicon rods are produced in a process in which a rotating cylinder of Si is slowly drawn from a heated bath. If the initial bath contains 62 kg Si, and a cylinder 17.5 cm in diameter is to be removed slowly from the melt at the rate of 3 mm per min, how long will it take to remove onehalf of the Si? What is the accumulation of Si in the melt?
