Heat Flow Calculation  

Example:
Calculate the Heat Flow for the given details.
Temperature of Hot Surface (F) = 5
Temperature of Cold Surface (F) = 2
Conductivity of Material Btuin./(h�ft2��F) = 3
Area (ft2) = 4
Thickness (inches) = 10
Solution:
Apply Formula:
Calculated Heat Flow= (Conductivity of Material*Area (ft2)*(Temperature of Hot Surface (F)Temperature of Cold Surface(F))/Thickness(inches))
Calculated Heat Flow = (3*4*52)/10
Calculated Heat Flow = 12*3/10
Calculated Heat Flow = 36/10
Calculated Heat Flow = 3.600 (Btu/h)
