Question:
4-0 stainless steel sutures used for orthopedic applications are subjected to a heat treating process. The sutures are drawn through an oven at a rate of 0.5 meters per minute. The oven temperature is kept at 700°C. The wire enters the oven at room temperature, 25°C, and exits the oven at 500°C. What is the rate of heat transfer to the wire? Note that a 4-0 suture has a diameter of 0.150 mm. Hint: You will need to use the following table. You can assume that stainless steel and mild steel have similar thermal properties. The answer is 25.5 W.
As an example, you can see an example of steel sutures manufactured by Ethicon here: https://www.jnjmedtech.com/en-US/product/surgical-stainless-steel-suture
