I'd like to calculate the "apparent temperature" of a material if you touched it, using the material's thermal conductions value (k).
I've found tables listing the thermal conduction of different materials (http://www.physicsclassroom.com/class/thermalP/Lesson-1/Rates-of-Heat-Transfer, and a small table here: http://cfbt-us.com/wordpress/?p=1110). How can I calculate what it might feel like to touch a block of Copper vs a brick or wood, all at the same temperature, such as 50 degrees fahrenheit.
Everything I've found either mentions in vague terms that "metal feels colder" (or hotter, given specific circumstances), or talks about finding the rate of the transfer between two substances. I'd love to be able to calculate "Touching cast iron at 40 degrees will feel like __ degrees to your fingers".
I'm guessing finding a precise value would be difficult because factors such as the thickness of the material, the pressure which you're touching, etc, would have an impact... but if there's a way to find a relatively accurate answer, that would be incredibly interesting!
