In a metal wire manufacturing facility, continuously drawn copper wire with a 2.5 mm diameter is annealed

Question:

In a metal wire manufacturing facility, continuously drawn copper wire with a 2.5 mm diameter is annealed by heating it from its initial temperature of 45°C to 400°C in a soaking oven. The oven inside air temperature is 700°C with an average heat transfer coefficient of h̅c = 45 W/m2•K. Estimate the soaking annealing time required. Also, if the oven is 3.5 m long and the drawn wire is continuously fed through the oven (entering at one end and pulled out at the other longitudinal end), what should be the drawing speed or velocity?
