Question

Principle of heat and mass transfer 7th solution

Answer 1

Step 1 of 3

Calculate the area of insulation.

Here, side length of the sheet is d.

Substitute 3 m for d.

Step 2 of 3

(a)

Calculate the heat flux through the insulated sheet.

Here,  is the temperature difference and kis the thermal conductivity.

Substitute  for  , 0.025 m for L, and  for k.

Therefore, the heat flux through the insulation sheet is  11.6 w/m²
