In the convection equation (or any of the heat transfer equations) q/A=h(Tf-Ts) I don't know what the heat transfer will be or what the surface temperature of the beam will be because they are both based on time. Is there another useful equation that I am missing?

You're saying I should focus on convection (with the hot or cold air around the beams) and radiation (from the sun). I looked into calculating the sun radiation and it gets very complicated when you consider the different angles throughout the day. Is there a simplified approach? Thank you for...

I was considering conduction through the layers of insulation. There will likely be a polystyrene insulation with an aluminum type duct wrap on the outside. You are right about the radiation and convection. I feel like I am making this way more complicated than it should be already. Does the...

To further explain this I have figured out the heat transfer to the beams (for summer design conditions) and from the beam (for winter design conditions) based on the allowed temperature ranges (52°F-92°F) with and without insulation (I have not factored in the additional heat from the heat...

I'm working on a problem involving steel structural members on the exterior of a building. I need to figure out how much insulation (for summer conditions) and possible heat tracing (for winter conditions) would be required to maintain minimum and maximum temperatures. I know I need to use the...
