I'm trying to calculate the effective Sky Temperature at a given point on the earth. All that I have been given so far is a rule of thumb for locations around the 30 to 45 deg N Latitude to be 10 to 20 deg C below that of ambient for a clear sky day. For a cloudy day, the effective sky...
I'm at a loss.
I have an object that is subject to solar radiation. I'm trying to understand what a good assumption for the heat flux would be. I have been told that a reasonable assumption would be 1000W/m^2. The surface of the object is painted white with (e=. 96 and Alpha=. 21). The surface...

I'm looking to weld 4130 (4" round bar) to a lower carbon steel (pipe) that is unknown. The required strength of the 4130 will call for it to be heat-treated. The required strength = 100 Ksi Yield. The question is that would it be better to heat treat the...
