Questions Related to Heat & Mass Transfer

Hey - This is a very urgent job and only bid if you can complete it in next 5 hours.

I have an assignment and there are three questions I cannot solve from that. I need some one who can quickly write answers to this in next 5 hours. This should not be difficult for the one who actually knows it.

I want proper and well written answers in word or pdf format.

1- What is meant by 1D conduction? Can radial or spherical geometries still have 1D conduction? Why or why not? If you were not told that a given problem had 1D conduction, what things might you think about to determine if it is 1D?

2 - Material Properties/Applications: What effect does the thermal conductivity have on the slope of the temperature profile in a given material? That is, does a higher thermal conductivity make the temperature profile flatter or steeper (i.e. is the temperature drop through the thickness of the material larger or smaller)? How might this impact your daily life?

3 - The thermal conductivity of air is ~.025 W/mK, whereas the thermal conductivity of a typical insulation material is ~.05 W/mK. That is, insulation materials have a higher thermal conductivity than air. Why then would it be advantageous to wrap a pipe in insulation rather than leave it sitting in air? Under what conditions would it be more advantageous to insulate something with air? (hint: think about double-paned windows)

The first question was if you can have 1 d current in a 3 d object, and the answer is yes, you can have three... Also because EM is complex you have six degrees of freedom. All objects described sphere, circle, hav Plus
