Question

A 3-in-diameter cylindrical wire is coated in 3 inches of polyethylene insulation. The wire can be modeled as a grey body with an emissivity of .85. Due to the electrical resistance, the wire is at a temperature of 300 degrees Celsius. The insulation is also a great body with an emissivity of .95, at a temperature of 40 degrees Celsius. (Assume F12=1). What is the heat flux (W/m^2) of the energy going from the wire to the insulation?

Expert Solution

Step 1: Given data:

Given:

D = 3 in = 0.0762 m (wire diameter)

T₁ = 300°C = 573 K

ε₁= 0.85 (wire emissivity)

T₂ = 40°C = 313 K

ε₂ = 0.95 (insulation emissivity)

F₁₂= 1
