I've found that conduction and convection are almost negligible, and that the solar flux is approximately 240 BTU/ft^2 per day. I'm trying to show that we will need to bury the pipe, so worst case scenario is what I've been looking at (no wind). Thank's for the replies, but I'm still not sure...
I'm working on a problem that deals with 132°F slurry flowing through black HDPE piping above ground for 1800ft. The max ambient temperature is 115°F, but the pipe is only useful for fluids up to 140°F. I need to show calculations for a temperature increase due to direct normal solar...
