What is the difference between heat flow and heat transfer?

WebFirst law of thermodynamics is thus conventionally stated as: “The change in internal energy of a closed system is equal to the energy added to it in the form of heat (Q) plus the work (W) done on the system by the surroundings.”. Mathematically, this can be put as. ∆E _ {internal} internal = Q + W.

Given the R-Value and area of a section of a building envelope, it is possible to calculate the rate of heat loss by conduction (in BTUs per hour) through that section at any given temperature difference. The equation for calculating heat loss is: Heat Loss = [ (Area) x (ΔT)] / R-Value. Area = the number of square feet.
