Consider a long duct constructed with diffuse and gray walls.
The width of each wall is 1 m. Heat transfer is from surface 1 to
surface 2, while surface 3 is completely insulated and cannot
absorb heat (which means q3 = 0).
Provide a sketch and state your assumptions
Determine the net radiation transfer from surface A1 per unit
length of the duct.
Determine the temperature of the insulated surface A3.
Use 1 sentence to describe the effect of changing...

heat transfer question
Consider a long duct constructed with diffuse and gray walls. The width of each wall is 1 m. Heat transfer is from surface 1 to surface 2, while surface 3 is completely insulated and cannot absorb heat (which means 93 = 0). A2, T2 = 700 K, £= 0.5 Aj, T1 = 1000 K, £1 = 0.33 -A2, T3, E3 = 0.8 a. Provide a sketch and state your assumptions b. Determine the net radiation transfer from...
