I have a cylinder of plastic (polypropylene). It is 1 meter in diameter and 1.25 meters long. It starts out at an even temperature of 100 C throughout. I put it into a 135 deg heated room with lots of air moving around it, and I hold it in the air so that every surface is exposed to the hot air. How long will it take for the plastic cylinder (inside and out) to reach the temperature of the room?
